Trong nội dung ngày 1 này, Laptrinhjavaweb sẽ cùng với các bạn giải các bài toán về mảng, chuỗi trong Java để ôn tập, cải thiện tư duy cũng như chuẩn bị cho các đợt đi phỏng vấn sắp tới nếu như công ty test logic thông qua các bài toàn này
Ngoài ra ngày 1 các bạn chỉ nên làm những thứ nhẹ nhàng, dễ chịu giúp tạo đà để sang các ngày sau học hiệu quả hơn
1. Tìm số lớn thứ 2 trong mảng
Mô tả đề bài
Cho 1 mảng: {7,5,6,1,4,2}
Kết quả mong muốn: 6
Hướng giải quyết
public static void main(String args[]) {
int[] arr1={7,5,6,1,4,2};
int secondHighest=findSecondLargestNumberInTheArray(arr1);
System.out.println("Second largest element in the array : "+ secondHighest);
}
public static int findSecondLargestNumberInTheArray(int array[]) {
int highest = Integer.MIN_VALUE;
int secondHighest = Integer.MIN_VALUE;
for (int i = 0; i < array.length; i++) {
if (array[i] > highest) {
secondHighest = highest;
highest = array[i];
} else if (array[i] > secondHighest && array[i]!=highest)
secondHighest = array[i];
}
return secondHighest;
}
2. Kiểm tra xem chuỗi có bao gồm các kí tự duy nhất hay không
Mô tả đề bài
Cho các chuỗi: "laptrinhjavaweb", "academy", "shop", "software"
Kết quả mong muốn:
- Chuỗi "laptrinhjavaweb có chứa các kí tự duy nhất không" : false
- Chuỗi "academy có chứa các kí tự duy nhất không" : false
- Chuỗi "shop có chứa các kí tự duy nhất không" : true
- Chuỗi "software có chứa các kí tự duy nhất không" : true
Hướng giải quyết
public static void main(String[] args) {
System.out.println("laptrinhjavaweb has all unique chars : "+ hasAllUniqueChars("laptrinhjavaweb"));
System.out.println("academy has all unique chars : "+ hasAllUniqueChars("academy"));
System.out.println("shop has all unique chars : "+ hasAllUniqueChars("shop"));
System.out.println("software has all unique chars : "+ hasAllUniqueChars("software"));
}
public static boolean hasAllUniqueChars (String word) {
for(int index=0;index < word.length(); index ++) {
char c =word.charAt(index);
if(word.indexOf(c) != word.lastIndexOf(c)) {
return false;
}
}
return true;
}

Ngày 3: Spring security trong spring boot, spring framework phần 2
- Link project: https://drive.google.com/file/d/1fXByUlDpaYwEE-P8yhTp7mhPyWf5bbdk/view?usp=sharing
1. Chỉnh sửa file index.jsp trong thư mục webapp:
<%@ taglib prefix="c" uri="http://java.sun.com/jsp/jstl/core"%>
<c:redirect url="/login"/>
2. Sử dụng DBMS MySql:
Tạo schema có tên: 7dayjavamasterv1
Trong file pom.xml, thêm dependency:
<dependency>
<groupId>mysql</groupId>
<artifactId>mysql-connector-java</artifactId>
<version>8.0.13</version>
</dependency>
<dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-data-jpa</artifactId>
</dependency>
3. Chỉnh sửa file application.properties trong thư mục resources:
spring.datasource.url = jdbc:mysql://localhost:3306/7dayjavamasterv1
spring.datasource.username = root
spring.datasource.password = 123456
#spring.jpa.hibernate.ddl-auto = none
spring.jpa.hibernate.ddl-auto = create
spring.jpa.properties.hibernate.dialect = org.hibernate.dialect.MySQL55Dialect
spring.jpa.properties.hibernate.enable_lazy_load_no_trans = true
spring.jpa.show-sql=true
spring.jpa.properties.hibernate.format_sql=true
4. Tạo package com.laptrinhjavaweb.entity, thêm class RoleEntity và UserEntity:
Class RoleEntity:
@Entity
@Table(name = "role")
public class RoleEntity {
@Id
@GeneratedValue(strategy = GenerationType.IDENTITY)
private Long id;
@Column(nullable = false)
private String name;
@Column(unique = true, nullable = false)
private String code;
@ManyToMany(mappedBy = "roles", fetch = FetchType.LAZY)
private List<UserEntity> users = new ArrayList<>();
public String getName() {
return name;
}
public void setName(String name) {
this.name = name;
}
public String getCode() {
return code;
}
public void setCode(String code) {
this.code = code;
}
public List<UserEntity> getUsers() {
return users;
}
public void setUsers(List<UserEntity> users) {
this.users = users;
}
public Long getId() {
return id;
}
public void setId(Long id) {
this.id = id;
}
}
Class UserEntity:
@Entity
@Table(name = "users")
public class UserEntity {
@Id
@GeneratedValue(strategy = GenerationType.IDENTITY)
private Long id;
@Column(name = "username", nullable = false, unique = true)
private String userName;
@Column(name = "fullname", nullable = false)
private String fullName;
@Column(name = "password", nullable = false)
private String password;
@Column(name = "status", nullable = false)
private Integer status;
@Column(name = "email", unique = true)
private String email;
@ManyToMany(fetch = FetchType.LAZY)
@JoinTable(name = "user_role",
joinColumns = @JoinColumn(name = "user_id", nullable = false),
inverseJoinColumns = @JoinColumn(name = "role_id", nullable = false))
private List<RoleEntity> roles = new ArrayList<>();
public String getUserName() {
return userName;
}
public void setUserName(String userName) {
this.userName = userName;
}
public String getFullName() {
return fullName;
}
public void setFullName(String fullName) {
this.fullName = fullName;
}
public String getPassword() {
return password;
}
public void setPassword(String password) {
this.password = password;
}
public Integer getStatus() {
return status;
}
public void setStatus(Integer status) {
this.status = status;
}
public List<RoleEntity> getRoles() {
return roles;
}
public void setRoles(List<RoleEntity> roles) {
this.roles = roles;
}
public String getEmail() {
return email;
}
public void setEmail(String email) {
this.email = email;
}
public Long getId() {
return id;
}
public void setId(Long id) {
this.id = id;
}
}
5. Run project để tạo database, sau đó cần sửa file application.properties trong thư mục resources:
spring.jpa.hibernate.ddl-auto = none
#spring.jpa.hibernate.ddl-auto = create
6. Insert data cho schema 7dayjavamasterv1:
use 7dayjavamasterv1;
insert into role(code,name) values('ADMIN','Quản trị hệ thống');
insert into role(code,name) values('USER','người dùng');
insert into users(username,password,fullname,status)
values('admin','$2a$10$/RUbuT9KIqk6f8enaTQiLOXzhnUkiwEJRdtzdrMXXwU7dgnLKTCYG','admin',1);
insert into users(username,password,fullname,status)
values('nguyenvana','$2a$10$/RUbuT9KIqk6f8enaTQiLOXzhnUkiwEJRdtzdrMXXwU7dgnLKTCYG','nguyen van a',1);
INSERT INTO user_role(user_id,role_id) VALUES (1,1);
INSERT INTO user_role(user_id,role_id) VALUES (2,2);
7. Trong file pom.xml, thêm dependency:
<dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-security</artifactId>
</dependency>
<dependency>
<groupId>org.modelmapper</groupId>
<artifactId>modelmapper</artifactId>
<version>0.7.4</version>
</dependency>
<dependency>
<groupId>org.springframework.security</groupId>
<artifactId>spring-security-taglibs</artifactId>
<version>4.2.16.RELEASE</version>
</dependency>
8. Tạo class WebSecurityConfig và class ModelMapperConfig trong packgage config:
Class WebSecurityConfig:
@Configuration
@EnableWebSecurity
public class WebSecurityConfig extends WebSecurityConfigurerAdapter {
@Bean
public UserDetailsService userDetailsService() {
return new CustomUserDetailService();
}
@Bean
public BCryptPasswordEncoder passwordEncoder() {
return new BCryptPasswordEncoder();
}
@Bean
public DaoAuthenticationProvider authenticationProvider() {
DaoAuthenticationProvider authProvider = new DaoAuthenticationProvider();
authProvider.setUserDetailsService(userDetailsService());
authProvider.setPasswordEncoder(passwordEncoder());
return authProvider;
}
@Override
protected void configure(AuthenticationManagerBuilder auth) {
auth.authenticationProvider(authenticationProvider());
}
@Override
protected void configure(HttpSecurity http) throws Exception {
http.csrf().disable()
.authorizeRequests()
.antMatchers("/user").hasRole("ADMIN")
.antMatchers("/trang-chu").hasAnyRole("ADMIN","USER")
.antMatchers("/article").hasAnyRole("ADMIN","USER")
.antMatchers("/login").permitAll()
.and()
.formLogin().loginPage("/login").usernameParameter("j_username")
.passwordParameter("j_password").permitAll()
.loginProcessingUrl("/j_spring_security_check")
.successHandler(myAuthenticationSuccessHandler())
.failureUrl("/login?incorrectAccount").and()
.logout().logoutUrl("/logout").deleteCookies("JSESSIONID")
.and().exceptionHandling().accessDeniedPage("/access-denied").and()
.sessionManagement().maximumSessions(1).expiredUrl("/login?sessionTimeout");
}
@Bean
public AuthenticationSuccessHandler myAuthenticationSuccessHandler(){
return new CustomSuccessHandler();
}
}
Class ModelMapperConfig:
@Configuration
@ComponentScan(basePackages = "com.laptrinhjavaweb")
public class ModelMapperConfig {
@Bean
public ModelMapper modelMapper(){
return new ModelMapper();
}
}
9. Thêm class RoleDTO, class UserDTO và MyUserDetail trong package dto:
Class RoleDTO:
public class RoleDTO {
private Long id;
private String name;
private String code;
public String getName() {
return name;
}
public void setName(String name) {
this.name = name;
}
public String getCode() {
return code;
}
public void setCode(String code) {
this.code = code;
}
public Long getId() {
return id;
}
public void setId(Long id) {
this.id = id;
}
}
Class UserDTO:
public class UserDTO {
private Long id;
private String userName;
private String email;
private String fullName;
private String password;
private Integer status;
private String roleCode;
private Map<String,String> roleDTOs;
private List<RoleDTO> roles = new ArrayList<>();
public String getUserName() {
return userName;
}
public void setUserName(String userName) {
this.userName = userName;
}
public String getEmail() {
return email;
}
public void setEmail(String email) {
this.email = email;
}
public String getFullName() {
return fullName;
}
public void setFullName(String fullName) {
this.fullName = fullName;
}
public String getPassword() {
return password;
}
public void setPassword(String password) {
this.password = password;
}
public Integer getStatus() {
return status;
}
public void setStatus(Integer status) {
this.status = status;
}
public List<RoleDTO> getRoles() {
return roles;
}
public void setRoles(List<RoleDTO> roles) {
this.roles = roles;
}
public Map<String, String> getRoleDTOs() {
return roleDTOs;
}
public void setRoleDTOs(Map<String, String> roleDTOs) {
this.roleDTOs = roleDTOs;
}
public String getRoleCode() {
return roleCode;
}
public void setRoleCode(String roleCode) {
this.roleCode = roleCode;
}
public Long getId() {
return id;
}
public void setId(Long id) {
this.id = id;
}
}
Class MyUserDetail:
public class MyUserDetail extends User {
public MyUserDetail(String username, String password, boolean enabled, boolean accountNonExpired, boolean credentialsNonExpired, boolean accountNonLocked, Collection<? extends GrantedAuthority> authorities) {
super(username, password, enabled, accountNonExpired, credentialsNonExpired, accountNonLocked, authorities);
}
private Long id;
private String fullName;
public Long getId() {
return id;
}
public void setId(Long id) {
this.id = id;
}
public String getFullName() {
return fullName;
}
public void setFullName(String fullName) {
this.fullName = fullName;
}
}
10. Tạo class UserRepository trong package repository:
public interface UserRepository extends JpaRepository<UserEntity, Long> {
UserEntity findOneByUserNameAndStatus(String name, int status);
}
11. Tạo package service, bên trong package này tạo package impl chứa class CustomUserDetailService và class UserService:
Class CustomUserDetailService:
@Service
public class CustomUserDetailService implements UserDetailsService {
@Autowired
private IUserService userService;
@Override
public UserDetails loadUserByUsername(String name) throws UsernameNotFoundException {
UserDTO userDTO = userService.findOneByUserNameAndStatus(name, 1);
if(userDTO == null){
throw new UsernameNotFoundException("Username not found");
}
List<GrantedAuthority> authorities = new ArrayList<>();
for(RoleDTO role: userDTO.getRoles()){
authorities.add(new SimpleGrantedAuthority("ROLE_"+role.getCode()));
}
MyUserDetail myUserDetail = new MyUserDetail(name,userDTO.getPassword(),true,true,true,true,authorities);
BeanUtils.copyProperties(userDTO, myUserDetail);
return myUserDetail;
}
}
Class UserService:
@Service
public class UserService implements IUserService {
@Autowired
private UserRepository userRepository;
@Autowired
private UserConverter userConverter;
@Override
public UserDTO findOneByUserNameAndStatus(String name, int status) {
UserEntity user = userRepository.findOneByUserNameAndStatus(name, status);
return userConverter.convertToDto(user);
}
}
Tạo interface IUserService trong package service:
public interface IUserService {
UserDTO findOneByUserNameAndStatus(String name, int status);
}
12. Tạo class UserConverter trong package converter:
@Component
public class UserConverter {
@Autowired
private ModelMapper modelMapper;
public UserDTO convertToDto (UserEntity entity){
UserDTO result = modelMapper.map(entity, UserDTO.class);
return result;
}
public UserEntity convertToEntity (UserDTO dto){
UserEntity result = modelMapper.map(dto, UserEntity.class);
return result;
}
}
13. Tạo package security, trong package này tạo package utils chứa class SecurityUtils:
public class SecurityUtils {
public static MyUserDetail getPrincipal() {
return (MyUserDetail) (SecurityContextHolder
.getContext()).getAuthentication().getPrincipal();
}
public static List<String> getAuthorities() {
List<String> results = new ArrayList<>();
List<GrantedAuthority> authorities = (List<GrantedAuthority>)
(SecurityContextHolder.getContext().getAuthentication().getAuthorities());
for (GrantedAuthority authority : authorities) {
results.add(authority.getAuthority());
}
return results;
}
}
Tạo class CustomSuccessHandler trong package security:
@Component
public class CustomSuccessHandler extends SimpleUrlAuthenticationSuccessHandler {
private RedirectStrategy redirectStrategy = new DefaultRedirectStrategy();
@Override
public void handle(HttpServletRequest request, HttpServletResponse response, Authentication authentication)
throws IOException {
String targetUrl = determineTargetUrl(authentication);
if (response.isCommitted()) {
System.out.println("Can't redirect");
return;
}
redirectStrategy.sendRedirect(request, response, targetUrl);
}
public String determineTargetUrl(Authentication authentication) {
return "/trang-chu";
}
public void setRedirectStrategy(RedirectStrategy redirectStrategy) {
this.redirectStrategy = redirectStrategy;
}
public RedirectStrategy getRedirectStrategy() {
return redirectStrategy;
}
}
14. Trong thư mục webapp/WEB-INF/views, thay đổi file home.jsp:
<%@ page import="com.laptrinhjavaweb.security.utils.SecurityUtils" %>

Ngày 4: Spring security trong spring boot, spring framework phần 3
Phần này giải thích các nội dung trong ngày 3, các bạn xem kỹ nội dung video sau buổi học để ôn tập
Ngày 5: Triển khai project lên java hosting
5.1 Mua hosting tại laptrinhjavawebsoftware
Chi tiết: http://laptrinhjavawebsoftware.com/java-hosting.html
Chú ý: bên "Laptrinhjavaweb Software" có tặng mã giảm 100.000 VNĐ cho các bạn tham gia chương trình, các bạn liên hệ để lấy mã giảm giá nhé
Sau khi mua java hosting xong, bạn có 2 lựa chọn
1. Nhờ kỹ thuật bên "Laptrinhjavaweb Software" xử lý hết luôn bao gồm: đưa code lên hosting và database
2. Tự làm để luôn chủ động trong mọi tình huống (xem chi tiết bên dưới nhé)
Đối với thao tác triển khai code lên hosting
5.2 Sau khi được cung cấp các thông tin cần thiết thì đăng nhập vào trang [tên miền]/manager/html để upload website
Lưu ý: đổi tên file WAR thành ROOT.war
5.3 Nếu đã từng upload rồi thì xóa phải cũ để upload file mới
Chọn Undeploy
5.4 Sau đó upload file mới
Chọn file ROOT.war và nhấn Deploy
Đối với thao tác triển khai database lên hosting
1. Sau khi được cung cấp các thông tin như: IP, port, username, password thì các bạn mở mysql dưới máy rồi thiết lập kết nối tới mysql trên hosting theo các thông tin được cung cấp
2. Sau khi thiêt lập kết nối tới mysql trên hosting thành công thì các bạn làm các bước giống như các bạn làm dưới local để có được database mong muốn
