spring-security与springmvc整合

一、导入pom坐标

        <dependency>
            <groupId>org.springframework.security</groupId>
            <artifactId>spring-security-web</artifactId>
            <version>5.0.1.RELEASE</version>
        </dependency>
        <dependency>
            <groupId>org.springframework.security</groupId>
            <artifactId>spring-security-config</artifactId>
            <version>5.0.1.RELEASE</version>
        </dependency>
        <dependency>
            <groupId>org.springframework.security</groupId>
            <artifactId>spring-security-core</artifactId>
            <version>5.0.1.RELEASE</version>
        </dependency>
        <dependency>
            <groupId>org.springframework.security</groupId>
            <artifactId>spring-security-taglibs</artifactId>
            <version>5.0.1.RELEASE</version>
        </dependency>

二、配置web.xml

注意:配置spring-security的过滤器时,filter-name的名称不能随意修改,只能为配置中所写的名称。

  <filter>
    <filter-name>springSecurityFilterChain</filter-name>
    <filter-class>org.springframework.web.filter.DelegatingFilterProxy</filter-class>
  </filter>
  <filter-mapping>
    <filter-name>springSecurityFilterChain</filter-name>
    <url-pattern>/*</url-pattern>
  </filter-mapping>

三、配置spring-security.xml配置信息

<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans"
	xmlns:security="http://www.springframework.org/schema/security"
	xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
	xsi:schemaLocation="http://www.springframework.org/schema/beans          
    http://www.springframework.org/schema/beans/spring-beans.xsd          
    http://www.springframework.org/schema/security          
    http://www.springframework.org/schema/security/spring-security.xsd">
    
    <!-- 配置不拦截的资源 -->
    <security:http pattern="/login.jsp" security="none"/>
    <security:http pattern="/failer.jsp" security="none"/>
    <security:http pattern="/css/**" security="none"/>
    <security:http pattern="/img/**" security="none"/>
    <security:http pattern="/plugins/**" security="none"/>
    
    <!-- 
    	配置具体的规则 
    	auto-config="true"	不用自己编写登录的页面,框架提供默认登录页面
    	use-expressions="false"	是否使用SPEL表达式
    -->
    <security:http auto-config="true" use-expressions="false">
    	<!-- 配置具体的拦截的规则 pattern="请求路径的规则" access="访问系统的人,必须有ROLE_USER的角色" -->
    	<security:intercept-url pattern="/**" access="ROLE_USER,ROLE_ADMIN"/>
    	
    	<!-- 定义跳转的具体的页面 -->
    	<security:form-login  
    		login-page="/login.jsp"
    		login-processing-url="/login.do"
    		default-target-url="/index.jsp"
    		authentication-failure-url="/failer.jsp"
    	/>
    	
    	<!-- 关闭跨域请求 -->
    	<security:csrf disabled="true"/>
    	
    	<!-- 退出 -->
    	<security:logout invalidate-session="true" logout-url="/logout.do" logout-success-url="/login.jsp" />
    	
    </security:http>
    
    <!-- 切换成数据库中的用户名和密码 -->
    <security:authentication-manager>
    	<security:authentication-provider user-service-ref="userService">
    		<!-- 配置加密的方式 -->
    		<security:password-encoder ref="passwordEncoder"/>
    	</security:authentication-provider>
    </security:authentication-manager>
    
    <!-- 配置加密类 -->
    <bean id="passwordEncoder" class="org.springframework.security.crypto.bcrypt.BCryptPasswordEncoder"/>
    

 </beans>   

四、配置自定义UserDetailService实现类

注意:该自定义的service中,@Service中的注解名称,必须与Spring-security.xml中指定的<security:authentication-provider user-service-ref="userService">名称必须相同。

@Service("userService")
public class UserServiceImpl implements UserDetailsService {


    @Override
    public UserDetails loadUserByUsername(String username) throws UsernameNotFoundException {
       //第一步:通过用户名,去数据库查询用户信息
        //第二步:根据用户信息,实例化,处理自己的用户对象封装成UserDetails
        //如果是使用未加密的帐号和密码校验,请在用户名和密码前面,添加一个标识{noop}
        //  User user=new User(userInfo.getUsername(),"{noop}"+userInfo.getPassword(),getAuthority(userInfo.getRoles()));
        User user = new User(登录用户名, 从数据库查询出来的用户密码, 用户状态,false表示无效,true表示有效, true, true, true, 获取当前登录用户的角色列表));
        return user;
    }

    //作用就是返回一个List集合,集合中装入的是角色描述
    public List<SimpleGrantedAuthority> getAuthority(List<Role> roles) {

        List<SimpleGrantedAuthority> list = new ArrayList<>();
        for (Role role : roles) {
            list.add(new SimpleGrantedAuthority("ROLE_" + role.getRoleName()));
        }
        return list;
    }
}

五、测试

1、重新登录系统,访问任何一个请求,如果直接都跳转到 login.jsp的登录界面,则表示框架整合成功

2、输入一个正确的帐号和密码,如果报403(权限不足),则表示当前用户配置的角色权限有问题,请检查自定义实现的UserDetailServiceImpl类中,获取的用户角色列表名称中,是否有spring-security.xml中<security:intercept-url pattern="/**" access="ROLE_USER,ROLE_ADMIN"/> 任何一个角色。
