shiro框架整合ssm框架

下面我通过一个web的maven项目来讲解如何将shiro整合ssm框架，具体结构如下图

一、引入依赖的jar包

二、配置web.xml

<?xml version="1.0" encoding="UTF-8"?>

<web-app version="2.4"
         xmlns="http://java.sun.com/xml/ns/j2ee"
         xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
         xsi:schemaLocation="http://java.sun.com/xml/ns/j2ee http://java.sun.com/xml/ns/j2ee/web-app_2_4.xsd">


  <!--shiro拦截器-->
  <filter>
    <filter-name>shiroFilter</filter-name>
    <filter-class>org.springframework.web.filter.DelegatingFilterProxy</filter-class>
  </filter>

  <filter-mapping>
    <filter-name>shiroFilter</filter-name>
    <url-pattern>/*</url-pattern>
  </filter-mapping>


  <!--spring配置监听器-->
  <listener>
    <listener-class>org.springframework.web.context.ContextLoaderListener</listener-class>
  </listener>

  <!--spring配置文件路径，启动时就加载-->
  <context-param>
    <param-name>contextConfigLocation</param-name>
    <param-value>classpath:spring.xml</param-value>
  </context-param>


  <!--springmvc的控制器-->
  <servlet>
    <servlet-name>springmvc</servlet-name>
    <servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>
    <init-param>
      <param-name>contextConfigLocation</param-name>
      <param-value>classpath:springmvc.xml</param-value>
    </init-param>
  </servlet>
  
  <servlet-mapping>
    <servlet-name>springmvc</servlet-name>
    <url-pattern>/</url-pattern>
  </servlet-mapping>

</web-app>

三、spring整合mybatis的配置文件，springmvc配置文件，mybatis配置文件，mabatis映射文件

1、spring整合mybatis的配置文件

<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans"
       xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
       xmlns:context="http://www.springframework.org/schema/context"
       xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans.xsd http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context.xsd">

    <!--扫描Service注解-->
    <context:component-scan base-package="com.imooc.service"/>

    <!--shiro的web过滤器-->
    <bean id="shiroFilter" class="org.apache.shiro.spring.web.ShiroFilterFactoryBean">
        <property name="securityManager" ref="securityManager"/>
        <property name="loginUrl" value="login.html"/>
        <property name="unauthorizedUrl" value="403.html"/>
        <property name="filterChainDefinitions">
            <value>
                <!--anon表示无需验证，authc表示需要验证-->
                /login.html = anon
                /sublogin = anon
                /* = authc
            </value>
        </property>
    </bean>

    <!--安全管理器-->
    <bean id="securityManager" class="org.apache.shiro.web.mgt.DefaultWebSecurityManager">
        <property name="realm" ref="realm"/>
    </bean>

    <!--自定义realm-->
    <bean id="realm" class="com.imooc.realm.CustomRealm">
        <property name="credentialsMatcher" ref="hashedCredentialsMatcher"/>
    </bean>

    <!--凭证匹配器-->
    <bean id="hashedCredentialsMatcher" class="org.apache.shiro.authc.credential.HashedCredentialsMatcher">
        <property name="hashAlgorithmName" value="md5"/>
        <property name="hashIterations" value="1"/>
    </bean>


    <!--数据库连接池-->
    <bean id="dataSource" class="com.alibaba.druid.pool.DruidDataSource">
        <property name="url" value="jdbc:mysql://localhost:3306/realm_test"/>
        <property name="username" value="root"/>
        <property name="password" value="123456"/>
    </bean>


    <!--sqlSessionFactory的形成，可看作spring和mybatis整合的重要一步-->
    <bean id="sqlSessionFactory" class="org.mybatis.spring.SqlSessionFactoryBean">
        <property name="dataSource" ref="dataSource"/>
        <property name="configLocation" value="classpath:mybatis-config.xml"/>
        <property name="typeAliasesPackage" value="com.imooc.entity"/>
        <property name="mapperLocations" value="classpath:mapper/*.xml"/>
    </bean>
    
    <!--自动扫描dao层，将对应的Mapper接口生成代理注入到Spring-->
    <bean class="org.mybatis.spring.mapper.MapperScannerConfigurer">
        <property name="sqlSessionFactoryBeanName" value="sqlSessionFactory"/>
        <property name="basePackage" value="com.imooc.dao"/>
    </bean>

</beans>

2、springmvc配置文件

<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans"
       xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
       xmlns:context="http://www.springframework.org/schema/context"
       xmlns:mvc="http://www.springframework.org/schema/mvc"
       xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans.xsd http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context.xsd http://www.springframework.org/schema/mvc http://www.springframework.org/schema/mvc/spring-mvc.xsd">

    <!--扫描Controller注解的控制器-->
    <context:component-scan base-package="com.imooc.controller"/>

    <!--设置配置方案-->
    <mvc:annotation-driven/>

    <!--找不到对应的Controller就扫描静态资源-->
    <mvc:resources mapping="/*" location="/"/>
</beans>

3、mybatis配置文件

<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE configuration
        PUBLIC "-//mybatis.org//DTD Config 3.0//EN"
        "http://mybatis.org/dtd/mybatis-3-config.dtd">
<configuration>

    <!--只是idea生成模板的默认配置，可忽略-->
    <settings>
        <!-- Globally enables or disables any caches configured in any mapper under this configuration -->
        <setting name="cacheEnabled" value="true"/>
        <!-- Sets the number of seconds the driver will wait for a response from the database -->
        <setting name="defaultStatementTimeout" value="3000"/>
        <!-- Enables automatic mapping from classic database column names A_COLUMN to camel case classic Java property names aColumn -->
        <setting name="mapUnderscoreToCamelCase" value="true"/>
        <!-- Allows JDBC support for generated keys. A compatible driver is required.
        This setting forces generated keys to be used if set to true,
         as some drivers deny compatibility but still work -->
        <setting name="useGeneratedKeys" value="true"/>
    </settings>

    <!-- Continue going here -->

</configuration>

4、mabatis映射文件

<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE mapper PUBLIC "-//mybatis.org//DTD Mapper 3.0//EN" "http://mybatis.org/dtd/mybatis-3-mapper.dtd">
<mapper namespace="com.imooc.dao.UserDao">

    <select id="getPasswordByName" parameterType="String" resultType="String">
        select password from users where username=#{username}
    </select>

    <select id="getRoles" parameterType="String" resultType="String">
        select role_name from user_roles where username=#{username}
    </select>

</mapper>

四、代码

 1、Controller层

package com.imooc.controller;

import com.imooc.entity.User;
import org.apache.shiro.SecurityUtils;
import org.apache.shiro.authc.UsernamePasswordToken;
import org.apache.shiro.subject.Subject;
import org.springframework.stereotype.Controller;
import org.springframework.web.bind.annotation.RequestBody;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RequestMethod;
import org.springframework.web.bind.annotation.ResponseBody;

@Controller
public class UserController {

    @RequestMapping(value="/sublogin",method= RequestMethod.POST,produces = "application/json;charset=utf-8")
    @ResponseBody
    public String userLogin(User user){
        UsernamePasswordToken token=new UsernamePasswordToken(user.getName(),user.getPassword());
        Subject subject= SecurityUtils.getSubject();
        try{
            subject.login(token);
        }catch (Exception e){
            return e.getMessage();
        }
        if(subject.hasRole("admin")){
            return "权限正确";
        }
        return "权限失败";
    }
}

2、Service层

package com.imooc.service;

import com.imooc.dao.UserDao;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Service;

import java.util.Set;

@Service
public class UserService {

    @Autowired
    private UserDao userDao;

    public Set<String> getRoles(String name) {
        Set<String> set=userDao.getRoles(name);
        return set;
    }

    public String getPasswordByName(String name) {
        String password=userDao.getPasswordByName(name);
        return password;
    }
}

3、自定义的Realm

package com.imooc.realm;

import com.imooc.dao.UserDao;
import com.imooc.service.UserService;
import org.apache.shiro.authc.AuthenticationException;
import org.apache.shiro.authc.AuthenticationInfo;
import org.apache.shiro.authc.AuthenticationToken;
import org.apache.shiro.authc.SimpleAuthenticationInfo;
import org.apache.shiro.authc.credential.HashedCredentialsMatcher;
import org.apache.shiro.authz.AuthorizationInfo;
import org.apache.shiro.authz.SimpleAuthorizationInfo;
import org.apache.shiro.crypto.hash.Md5Hash;
import org.apache.shiro.realm.AuthorizingRealm;
import org.apache.shiro.subject.PrincipalCollection;
import org.apache.shiro.util.ByteSource;
import org.springframework.beans.factory.annotation.Autowired;

import javax.annotation.Resource;
import java.util.ArrayList;
import java.util.HashMap;
import java.util.HashSet;
import java.util.Set;

public class CustomRealm extends AuthorizingRealm {

    @Autowired
    private UserService userService;

    //判断是否有角色权限
    protected AuthorizationInfo doGetAuthorizationInfo(PrincipalCollection principalCollection) {
        String name = (String) principalCollection.getPrimaryPrincipal();
        Set<String> roles = getRoleByName(name);
        SimpleAuthorizationInfo simpleAuthorizationInfo = new SimpleAuthorizationInfo();
        simpleAuthorizationInfo.setRoles(roles);
        return simpleAuthorizationInfo;
    }


    private Set<String> getRoleByName(String name) {
        Set<String> set = userService.getRoles(name);
        return set;
    }


    //判断是否有登陆权限
    protected AuthenticationInfo doGetAuthenticationInfo(AuthenticationToken authenticationToken) throws AuthenticationException {
        String name = (String) authenticationToken.getPrincipal();
        String password = getPassword(name);
        if (password == null) {
            return null;
        }
        SimpleAuthenticationInfo simpleAuthenticationInfo = new SimpleAuthenticationInfo(name, password, "abc");
        simpleAuthenticationInfo.setCredentialsSalt(ByteSource.Util.bytes(name));
        return simpleAuthenticationInfo;
    }

    private String getPassword(String name) {
        String password=userService.getPasswordByName(name);
        return password;
    }

4、Dao层

package com.imooc.dao;

import java.util.ArrayList;
import java.util.Set;

public interface UserDao {

    public String getPasswordByName(String name);

    public Set<String> getRoles(String name);
}

5、界面

<!DOCTYPE html>
<html lang="en">
<head>
    <meta charset="UTF-8">
    <title>登陆</title>
</head>
<body>

    <form action="sublogin" method="post">
        用户名：<input type="text" name="name"/>
        密码： <input type="password" name="password"/>
        <input type="submit" value="登陆">
    </form>

</body>
</html>

启动成功后如下：
