SpringSecurity
一、 概述
我学习SpringSecurity大概分为四部分:
- 配置SpringSecurity环境,
- SpringSecurity认证
- 用户注销和控制权限
- RememberMe功能的实现
二、SpringSecurity环境搭建
最终目录大概如下
我们需要配置如下: template和static文件会在后面发
1.配置template文件
2.导入Pom.xml依赖
这里只需要导入web依赖和thymeleaf依赖就可以了
<!-- thymeleaf模板-->
<dependency>
<groupId>org.thymeleaf</groupId>
<artifactId>thymeleaf-spring5</artifactId>
</dependency>
<dependency>
<groupId>org.thymeleaf.extras</groupId>
<artifactId>thymeleaf-extras-java8time</artifactId>
</dependency>
<!-- web-->
<dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-web</artifactId>
</dependency>
<dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-test</artifactId>
<scope>test</scope>
</dependency>
3.配置RouterController层
package com.kuang.controller;
import org.springframework.stereotype.Controller;
import org.springframework.web.bind.annotation.PathVariable;
import org.springframework.web.bind.annotation.RequestMapping;
@Controller
public class RouterController {
// 返回到的某页
@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;
}
// 这个level是随便写的只不过需要网页中的和这个对应
@RequestMapping("/level3/{id}")
public String level3(@PathVariable("id") int id){
return "views/level3/"+id;
}
}
4.配置完测试
输入网址: http://localhost:8080/ 可以跳转到正确页面,并且图各种vip1可以点击进去就可以了
三、 权限认证
1.在pom.xml加入下面依赖
<!-- 配置SpringSecurity依赖-->
<dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-security</artifactId>
</dependency>
2.配置config中 SecurityConfig
首先先继承WebSecurityConfigurereAdapter,源码什么的太麻烦了我就不拔了。
然后重写configure中有http和configure中有AuthenticationManagerBuilder方法
package com.kuang.config;
//继承了WebSecuritiyConfigurer并且实现了@EnableWebSecurity注解
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;
//这里是配置EnableSecurtiy适配器
@EnableWebSecurity
public class SecurityConfig extends WebSecurityConfigurerAdapter {
@Override
protected void configure(HttpSecurity http) throws Exception {
//我这里要定制首页所有人可以访问
//authorize是授权的意思
//添加相对应的匹配者有相对应的功能
http.authorizeRequests()
.antMatchers("/").permitAll()
.antMatchers("/level1/**").hasRole("vip1")
.antMatchers("/level2/**").hasRole("vip2")
.antMatchers("/level3/**").hasRole("vip3");
//这些都是SpringSecurity中jar需要的
//如果认证失败了就返回tologin页面
http.formLogin();
}
//有授权就有认证
//通过auth.inMemoryAuthentication认证
//然后是账号密码等级
//注意 需要and()拼接
//在SpringSecurity5新增了加密方式
//需要加密
@Override
protected void configure(AuthenticationManagerBuilder auth) throws Exception {
//数据正常情况是在数据库里面存
//需要在后面跟上passwordEncoder(new BCryptPasswordEncoder())
//在密码框里面输入password(new BCryptPasswordEncoder().encode("123456"))
//当然编码方式有很多种 我只是挑选了其中的一个
auth.inMemoryAuthentication().passwordEncoder(new BCryptPasswordEncoder())
.withUser("clearlove").password(new BCryptPasswordEncoder().encode("123456")).roles("vip1","vip3")
.and()
.withUser("admin").password(new BCryptPasswordEncoder().encode("123456")).roles("vip1","vip2","vip3")
.and()
.withUser("ylsl").password(new BCryptPasswordEncoder().encode("123456")).roles("vip1");
}
}
四、用户注销和控制权限
1.配置pom.xml
pom.xml中新增springsecurity-thymeleaf整合包
<!-- thymeleaf和springsecurity整合包-->
<!-- 作用:主要是将对应的等级匹配相对应的板块-->
<!-- https://mvnrepository.com/artifact/org.thymeleaf.extras/thymeleaf-extras-springsecurity4 -->
<!-- 使用spring5的jar包可以解决显示不了sec:authorization的问题-->
<dependency>
<groupId>org.thymeleaf.extras</groupId>
<artifactId>thymeleaf-extras-springsecurity5</artifactId>
<version>3.0.4.RELEASE</version>
</dependency>
2.配置RouteController
这里因为导入了thymeleaf-springsecurity的缘故,
所以我们可以使用RouteController的方法进行登录和注册
package com.kuang.config;
//继承了WebSecuritiyConfigurer并且实现了@EnableWebSecurity注解
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;
//这里是配置EnableSecurtiy适配器
@EnableWebSecurity
public class SecurityConfig extends WebSecurityConfigurerAdapter {
@Override
protected void configure(HttpSecurity http) throws Exception {
//我这里要定制首页所有人可以访问
//authorize是授权的意思
//添加相对应的匹配者有相对应的功能
http.authorizeRequests()
.antMatchers("/").permitAll()
.antMatchers("/level1/**").hasRole("vip1")
.antMatchers("/level2/**").hasRole("vip2")
.antMatchers("/level3/**").hasRole("vip3");
//这里是新增的部分
//定制自动登录页
http.formLogin().loginPage("/toLogin").usernameParameter("user").passwordParameter("pwd").loginProcessingUrl("/login");
//如果认证失败了就返回tologin页面
// http.formLogin();
//开启注销功能
http.logout().logoutSuccessUrl("/");
}
//有授权就有认证
//通过auth.inMemoryAuthentication认证
//然后是账号密码等级
//注意 需要and()拼接
//在SpringSecurity5新增了加密方式
//需要加密
@Override
protected void configure(AuthenticationManagerBuilder auth) throws Exception {
//数据正常情况是在数据库里面存
//需要在后面跟上passwordEncoder(new BCryptPasswordEncoder())
//在密码框里面输入password(new BCryptPasswordEncoder().encode("123456"))
//当然编码方式有很多种 我只是挑选了其中的一个
auth.inMemoryAuthentication().passwordEncoder(new BCryptPasswordEncoder())
.withUser("clearlove").password(new BCryptPasswordEncoder().encode("123456")).roles("vip1","vip3")
.and()
.withUser("admin").password(new BCryptPasswordEncoder().encode("123456")).roles("vip1","vip2","vip3")
.and()
.withUser("ylsl").password(new BCryptPasswordEncoder().encode("123456")).roles("vip1");
}
}
3.权限控制

<script th:src="@{/qinjiang/js/jquery-3.1.1.min.js}"></script>
<script th:src="@{/qinjiang/js/semantic.min.js}"></script>
</body>
</html>
- 首先配置th:sec的环境
<html lang="en"
xmlns:th="http://www.thymeleaf.org"
xmlns:sec="http://www.thymeleaf.org/thymeleaf-extras-springsecurity4"
>
- 然后,通过sec:authorize来控制属性
<div class="column" sec:authorize="hasRole('vip3')">
- 这个是显示相对应的用户名和权限
<div sec:authorize="isAuthenticated()">
<a class="item">
用户名:<span sec:authentication="name"></span>
<!-- 这里是principal.authorities认证-->
权限: <span sec:authentication="principal.authorities"></span>
</a>
</div>
四、remeberme和主页定制
package com.kuang.config;
//继承了WebSecuritiyConfigurer并且实现了@EnableWebSecurity注解
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;
//这里是配置EnableSecurtiy适配器
@EnableWebSecurity
public class SecurityConfig extends WebSecurityConfigurerAdapter {
@Override
protected void configure(HttpSecurity http) throws Exception {
//我这里要定制首页所有人可以访问
//authorize是授权的意思
//添加相对应的匹配者有相对应的功能
http.authorizeRequests()
.antMatchers("/").permitAll()
.antMatchers("/level1/**").hasRole("vip1")
.antMatchers("/level2/**").hasRole("vip2")
.antMatchers("/level3/**").hasRole("vip3");
//定制自动登录页
http.formLogin().loginPage("/toLogin").usernameParameter("user").passwordParameter("pwd").loginProcessingUrl("/login");
//如果认证失败了就返回tologin页面
// http.formLogin();
//开启注销功能
http.logout().logoutSuccessUrl("/");
http.csrf().disable(); //关闭跨站请求攻击的功能
//勾选rememberme登录的时候,向cookie注入了的值
http.rememberMe().rememberMeParameter("remember"); //记住我功能的实现
}
//有授权就有认证
//通过auth.inMemoryAuthentication认证
//然后是账号密码等级
//注意 需要and()拼接
//在SpringSecurity5新增了加密方式
//需要加密
@Override
protected void configure(AuthenticationManagerBuilder auth) throws Exception {
//数据正常情况是在数据库里面存
//需要在后面跟上passwordEncoder(new BCryptPasswordEncoder())
//在密码框里面输入password(new BCryptPasswordEncoder().encode("123456"))
//当然编码方式有很多种 我只是挑选了其中的一个
auth.inMemoryAuthentication().passwordEncoder(new BCryptPasswordEncoder())
.withUser("clearlove").password(new BCryptPasswordEncoder().encode("123456")).roles("vip1","vip3")
.and()
.withUser("admin").password(new BCryptPasswordEncoder().encode("123456")).roles("vip1","vip2","vip3")
.and()
.withUser("ylsl").password(new BCryptPasswordEncoder().encode("123456")).roles("vip1");
}
}
