<!--thymeleaf-->
<dependency>
<groupId>org.thymeleaf</groupId>
<artifactId>thymeleaf-spring5</artifactId>
</dependency>
<dependency>
<groupId>org.thymeleaf.extras</groupId>
<artifactId>thymeleaf-extras-java8time</artifactId>
</dependency>
import org.springframework.stereotype.Controller;
import org.springframework.web.bind.annotation.PathVariable;
import org.springframework.web.bind.annotation.RequestMapping;
@Controller
public class RouterController {
@RequestMapping({"/","/index"})
public String index() {
return "index";
}
@RequestMapping("/toLogin")
public String toLogin() {
return "views/login";
}
@RequestMapping("/level1/{id}")
public String level1(@PathVariable("id") int id) {
return "views/level1/"+id;
}
@RequestMapping("/level2/{id}")
public String level2(@PathVariable("id") int id) {
return "views/level2/"+id;
}
@RequestMapping("/level3/{id}")
public String level3(@PathVariable("id") int id) {
return "views/level3/"+id;
}
}
引入Spring Security模块
<dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-security</artifactId>
</dependency>
2.编写 Spring Security 配置类
参考官网
帮助文档
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.EnableWebSecurity;
import org.springframework.security.config.annotation.web.configuration.WebSecurityConfigurerAdapter;
import org.springframework.security.crypto.bcrypt.BCryptPassWordEncoder;
// 开启WebSecurity模式
@EnableWebSecurity //aop 拦截器
public class SecurityConfig extends WebSecurityConfigurerAdapter {
//链式编程
@Override
protected void configure(HttpSecurity http) throws Exception {
}
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.EnableWebSecurity;
import org.springframework.security.config.annotation.web.configuration.WebSecurityConfigurerAdapter;
import org.springframework.security.crypto.bcrypt.BCryptPasswordEncoder;
// 开启WebSecurity模式
@EnableWebSecurity //AOP 拦截器
public class SecurityConfig extends WebSecurityConfigurerAdapter {
//链式编程
@Override
protected void configure(HttpSecurity http) throws Exception {
}
3.定制请求的授权规则
//链式编程
@Override
protected void configure(HttpSecurity http) throws Exception {
//首页所有人可以访问,功能页面只有对应的人可以访问
//请求授权的规则
http.authorizeRequests().antMatchers("/").permitAll()
.antMatchers("/level1
@Override //认证 密码编码 PassWordEncoder
protected void configure(AuthenticationManagerBuilder auth) throws Exception {
auth.inMemoryAuthentication().passwordEncoder(new BCryptPasswordEncoder())
.withUser("yang").password(new BCryptPasswordEncoder().encode("123456")).roles("vip2","vip3")
.and()
.withUser("root").password(new BCryptPasswordEncoder().encode("123456")).roles("vip1","vip2","vip3")
.and()
.withUser("guest").password(new BCryptPasswordEncoder().encode("123456")).roles("vip1");
}
开启自动配置的注销的功能
@EnableWebSecurity //AOP 拦截器
public class SecurityConfig extends WebSecurityConfigurerAdapter {
//链式编程
@Override
protected void configure(HttpSecurity http) throws Exception {
//首页所有人可以访问,功能页面只有对应的人可以访问
//请求授权的规则
http.authorizeRequests().antMatchers("/").permitAll()
.antMatchers("/level1
@Controller
public class RouterController {
@RequestMapping({"/","/index"})
public String index() {
return "index";
}
@RequestMapping("/toLogin")
public String toLogin() {
return "views/login";
}
@RequestMapping("/level1/{id}")
public String level1(@PathVariable("id") int id) {
return "views/level1/"+id;
}
@RequestMapping("/level2/{id}")
public String level2(@PathVariable("id") int id) {
return "views/level2/"+id;
}
@RequestMapping("/level3/{id}")
public String level3(@PathVariable("id") int id) {
return "views/level3/"+id;
}
}
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.EnableWebSecurity;
import org.springframework.security.config.annotation.web.configuration.WebSecurityConfigurerAdapter;
import org.springframework.security.crypto.bcrypt.BCryptPasswordEncoder;
@EnableWebSecurity //AOP 拦截器
public class SecurityConfig extends WebSecurityConfigurerAdapter {
//链式编程
@Override
protected void configure(HttpSecurity http) throws Exception {
//首页所有人可以访问,功能页面只有对应的人可以访问
//请求授权的规则
http.authorizeRequests().antMatchers("/").permitAll()
.antMatchers("/level1
@Override //认证 密码编码 PassWordEncoder
protected void configure(AuthenticationManagerBuilder auth) throws Exception {
auth.inMemoryAuthentication().passwordEncoder(new BCryptPasswordEncoder())
.withUser("yang").password(new BCryptPasswordEncoder().encode("123456")).roles("vip2","vip3")
.and()
.withUser("root").password(new BCryptPasswordEncoder().encode("123456")).roles("vip1","vip2","vip3")
.and()
.withUser("guest").password(new BCryptPasswordEncoder().encode("123456")).roles("vip1");
}
