如何在SpringBoot项目中使用SpringSecurity？很多新手对此不是很清楚，为了帮助大家解决这个难题，下面小编将为大家详细讲解，有这方面需求的人可以来学习下，希望你能有所收获。
依赖
<dependencies> <dependency> <groupId>org.springframework.boot</groupId> <artifactId>spring-boot-starter-web</artifactId> </dependency> <!-- Thymeleaf --> <dependency> <groupId>org.thymeleaf</groupId> <artifactId>thymeleaf-spring5</artifactId> </dependency> <dependency> <groupId>org.thymeleaf.extras</groupId> <artifactId>thymeleaf-extras-java8time</artifactId> </dependency> <!-- SpringSecurity --> <dependency> <groupId>org.springframework.boot</groupId> <artifactId>spring-boot-starter-security</artifactId> </dependency> <!-- Thymeleaf 与 SpringSecurity 整合包 --> <dependency> <groupId>org.thymeleaf.extras</groupId> <artifactId>thymeleaf-extras-springsecurity5</artifactId> <version>3.0.4.RELEASE</version> </dependency> <dependency> <groupId>org.springframework.boot</groupId> <artifactId>spring-boot-starter-test</artifactId> <scope>test</scope> <exclusions> <exclusion> <groupId>org.junit.vintage</groupId> <artifactId>junit-vintage-engine</artifactId> </exclusion> </exclusions> </dependency> </dependencies>
Controller：
package com.blu.controller;
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;
}
}SecurityConfig：
package com.blu.config;
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
public class SecurityConfig extends WebSecurityConfigurerAdapter{
/**
* 授权
*/
@Override
protected void configure(HttpSecurity http) throws Exception {
//所有人可以访问首页，功能页需要指定权限才可以访问
http.authorizeRequests()
.antMatchers("/").permitAll()
.antMatchers("/level1/**").hasRole("vip1")
.antMatchers("/level2/**").hasRole("vip2")
.antMatchers("/level3/**").hasRole("vip3");
//没有权限将默认跳转至登录页，需要开启登录的页面
//loginPage设置跳转至登录页的请求（默认为/login）
//usernameParameter和passwordParameter配置登录的用户名和密码参数名称，默认就是username和password
//loginProcessingUrl配置登录请求的url，需要和表单提交的url一致
http.formLogin().loginPage("/tologin")
.usernameParameter("username")
.passwordParameter("password")
.loginProcessingUrl("/login");
//禁用CSRF保护
http.csrf().disable();
//开启注销功能和注销成功后的跳转页面（默认为登录页面）
http.logout().logoutSuccessUrl("/");
//开启记住我功能，Cookie默认保存两周
http.rememberMe().rememberMeParameter("remember");
}
/**
* 认证
*/
@Override
protected void configure(AuthenticationManagerBuilder auth) throws Exception {
auth.inMemoryAuthentication().passwordEncoder(new BCryptPasswordEncoder())
.withUser("BLU").password(new BCryptPasswordEncoder().encode("123456")).roles("vip2","vip3")
.and()
.withUser("root").password(new BCryptPasswordEncoder().encode("111111")).roles("vip1","vip2","vip3")
.and()
.withUser("guest").password(new BCryptPasswordEncoder().encode("111222")).roles("vip1");
}
}注：以上方式认证的用户和角色信息是存储在内存中的，在实际开发中应该从数据库中获取，详见：SpringSecurity从数据库中获取用户信息进行验证
