I. Mục tiêu:
Chúng ta sẽ tạo ứng dụng web SpringBoot MVC như bên dưới:
Với 5 urls:
- "/": được truy cập bởi tất cả mọi người.
- "/login": trang dùng để login.
- "/user": phải xác thực và được truy cập với người dùng có ROLE là {USER, ADMIN}.
- "/admin": được truy cập bởi người dùng có ROLE là ADMIN.
- "/403": HTTP Error 403 cấm truy cập.
II. Thực hành:
Các bước thực hiện:
- Tạo project Spring Boot.- Tạo Controller.
- Tạo các Pages View.
- Cấu hình WebSecurity.
1. Tạo project Spring Boot.
Sử dụng IDE ưu thích của bạn để tạo project SpringBoot với các dependencies như bên dưới:
<dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-security</artifactId>
</dependency>
<dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-thymeleaf</artifactId>
</dependency>
<dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-web</artifactId>
</dependency>
|
2. Tạo Controller.
package com.mpt.springsecurity.controller;
import org.springframework.stereotype.Controller;
import org.springframework.web.bind.annotation.RequestMapping;
@Controller
public class WebController {
@RequestMapping(value={"/","home"})
public String home(){
return "home";
}
@RequestMapping(value="/user")
public String user(){
return "user";
}
@RequestMapping(value="/admin")
public String admin(){
return "admin";
}
@RequestMapping(value="/login")
public String login(){
return "login";
}
@RequestMapping(value="/403")
public String Error403(){
return "403";
}
}
3. Tạo các trang View.
home.html
<!DOCTYPE html>
<html xmlns="http://www.w3.org/1999/xhtml"
xmlns:th="http://www.thymeleaf.org"
xmlns:sec="http://www.thymeleaf.org/thymeleaf-extras-springsecurity3">

<title>Security with Spring Boot</title>

<a style="color: blue" th:href="@{/user}">User Page</a>
<br />

<a style="color: blue" th:href="@{/}">Home</a>
<form th:action="@{/logout}" method="post">
<input type="submit" value="Sign Out" />

<a style="color: blue" th:href="@{/}">Home</a>
<form th:action="@{/logout}" method="post">
<input type="submit" value="Sign Out" />
</form>
</body>
</html>
4. Cấu hình WebSecurity.
Chúng ta sử dụng WebSecurityConfigurerAdapter để tạo ra một WebSecurityConfigurerỨng dụng web này có 2 người dùng:
- Admin: admin/admin.
- User: user/user.
package com.mpt.springsecurity.config;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.context.annotation.Configuration;
import org.springframework.security.config.annotation.authentication.builders
.AuthenticationManagerBuilder;
import org.springframework.security.config.annotation.web.builders.HttpSecurity;
import org.springframework.security.config.annotation.web.configuration
.WebSecurityConfigurerAdapter;
@Configuration
public class SecurityConfig extends WebSecurityConfigurerAdapter {
@Override
protected void configure(HttpSecurity http) throws Exception {
http
.authorizeRequests()
.antMatchers("/","/home").permitAll()
.antMatchers("/admin").hasRole("ADMIN")
.anyRequest().authenticated()
.and()
.formLogin()
.loginPage("/login")
.permitAll()
.and()
.logout()
.permitAll();
http.exceptionHandling().accessDeniedPage("/403");
}
@Autowired
public void configureGlobal(AuthenticationManagerBuilder auth)
throws Exception {
auth
.inMemoryAuthentication()
.withUser("user").password("{noop}user").roles("USER")
.and()
.withUser("admin").password("{noop}admin").roles("ADMIN");
}
}
