其实Shiro整合到Spring中并没有想象的那么困难,整到Spring中后,我们自定义的realm啊、securityManager啊等等都会交给spring去管理了,包括我们需要指定哪些url需要做什么样的验证,都是交给spring,也就是说,完全可以摆脱原来的那个.ini配置文件了,会觉得非常清爽,非常有逻辑。好了,下面开始整,Shiro部分参考了它的官方文档:http://shiro.apache.org/spring.html。
1. 整个工程目录结构
首先看一下整个工程的目录结构,先在宏观上对整体有个把握。
2. 配置文件
首先来完成一些配置文件,先从pom.xml开始,我已经用注释将它们归归类了,很清晰。
2.1 pom.xml

spring的配置文件中,我主要来说明一下shiro这一部分,因为其他部分都一样,扫描bean,配置数据源相关的,配置事务等等。我把上面shiro部分截图下来了:
从这部分的配置可以看出,其实就是和上一节中在.ini文件中配置的一样的,只不过现在换成让spring去管理了,也很好理解,当然这里自定义的MyRealm还没写,因为MyRealm中需要有关于数据库的操作,所以下面先把mybatis部分整合好(其实加上MyRealm,shiro部分已经整合完了~)。
3. 整合MyBatis
3.1 全局配置文件
首先配置一下mybatis的全局配置文件mybatis-config.xml,因为数据源啥的都交给spring管理了,所以全局配置文件就比较清爽了,当然还有一些设置上的东西,就不配置了,这个要看具体实际中使用的时候在配置。
<?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>
<typeAliases>
<package name="demo.entity"/>
</typeAliases>
</configura
3.2 配置mapper映射文件
配置一下UserMapper.xml
<?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="demo.dao.UserDao">
<select id="getByUsername" parameterType="String" resultType="User">
select * from t_user where username=#{username}
</select>
<select id="getRoles" parameterType="String" resultType="String">
select r.rolename from t_user u,t_role r where u.role_id=r.id and u.username=#{username}
</select>
<select id="getPermissions" parameterType="String" resultType="String">
select p.permissionname from t_user u,t_role r,t_permission p where u.role_id=r.id and p.role_id=r.id and u.username=#{username}
</select>
</mapper>

由配置可知,我们指定的是demo.dao.UserDao这个类,扫描mapper类是交给spring管理的,所以mapper接口可以不用和mapper映射文件同名且放到同一目录下,如果是交给mybatis管理我测试过是需要这么做的,在我之前mybatis的博文中也有提到这些。接下来就是写dao接口了(其实就是mapper映射文件对应的mapper接口)。
3.3 mapper接口
public interface UserDao {
public User getByUsername(String username);
public Set<String> getRoles(String username);
public Set<String> getPermissions(String username);
}
只需要写接口即可,不需要写实现,spring的配置文件中会去扫描mapper,会自动创建一个代理对象来执行相应的方法,要注意的是这个接口中的方法名要和上面mapper映射文件中的id号一样的,否则是无法映射到具体的statement上面的,会报错的。
3.4 po类
这里就写一个简单的User类,数据库中的存储信息可以参考上一篇博文,跟那边一样的。
public class User {
private Integer id;
private String username;
private String password;
}
3.5 完成service
顺带着把service层也完善了,这里我就写实现类了,接口就不写了。
@Service("userService")
public class UserServiceImpl implements UserService{
@Resource
private UserDao userDao;
public User getByUsername(String username) {
return userDao.getByUsername(username);
}
public Set<String> getRoles(String username) {
return userDao.getRoles(username);
}
public Set<String> getPermissions(String username) {
return userDao.getPermissions(username);
}
}

在service的实现类中,注入刚刚写好的dao接口即可调用其中的方法了,使用的是spring自动创建的代理对象去执行的。
4 整合SpringMVC
4.1 配置文件
上面的工作做完了后,其实需要写一个测试程序来测试一下能否正确访问数据库,因为整合必须步步为营。由于这个比较简单,我就不写测试程序了。因为前面web.xml配置中已经加入springmvc的支持了,所以这里直接写一下spring-mvc.xml配置文件即可:
<?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:p="http://www.springframework.org/schema/p"
xmlns:aop="http://www.springframework.org/schema/aop"
xmlns:context="http://www.springframework.org/schema/context"

xsi:schemaLocation="

http://www.springframework.org/schema/tx http://www.springframework.org/schema/tx/spring-tx-4.0.xsd">
<context:component-scan base-package="demo.controller" />
<bean id="viewResolver"
class="org.springframework.web.servlet.view.InternalResourceViewResolver">
<property name="prefix" value="/" />
<property name="suffix" value=".jsp"></property>
</bean>
</beans>

我这里只配置了扫描包,没有配映射器和适配器,也没有写那个<mvc:annotation-driven></mvc:annotation-driven>
注解驱动,也是可以执行的,我在网上没查到原因,也没去看源码,我的猜测是springmvc中可能有默认的映射器和适配器。如果有看过源码的朋友,请不吝赐教。
4.2 完成controller
配置好了后,就完成controller了,一个controller即可,因为一个controller中可以写很多方法。
@Controller
@RequestMapping("/user")
public class UserController {
@RequestMapping("/login")
public String login(User user, HttpServletRequest request) {
Subject subject = SecurityUtils.getSubject();
UsernamePasswordToken token = new UsernamePasswordToken(user.getUsername(), user.getPassword());
try{
subject.login(token);
request.getSession().setAttribute("user", user);
return "success";
}catch(Exception e){
e.printStackTrace();
request.getSession().setAttribute("user", user);
request.setAttribute("error", "用户名或密码错误!");
return "login";
}
}
@RequestMapping("/logout")
public String logout(HttpServletRequest request) {
request.getSession().invalidate();
return "index";
}
@RequestMapping("/admin")
public String admin(HttpServletRequest request) {
return "success";
}
@RequestMapping("/student")
public String student(HttpServletRequest request) {
return "success";
}
@RequestMapping("/teacher")
public String teacher(HttpServletRequest request) {
return "success";
}
}

4.2 完成自定义realm
终于可以写自己的realm了,上面用户登录会执行一个subject.login(token);
这里会跳转到我们自定义的realm中,接下来就来定义一下我们自己的realm,由于这里是和mybatis整合了,所以不需要原来的那个DbUtil去连接数据库了,直接使用mybatis中的mapper接口,也就是上面我们写的dao。
public class MyRealm extends AuthorizingRealm {
@Resource
private UserService userService;
@Override
protected AuthorizationInfo doGetAuthorizationInfo(
PrincipalCollection principals) {
String username = (String) principals.getPrimaryPrincipal();
SimpleAuthorizationInfo authorizationInfo = new SimpleAuthorizationInfo();
authorizationInfo.setRoles(userService.getRoles(username));
authorizationInfo.setStringPermissions(userService.getPermissions(username));
return authorizationInfo;
}
@Override
protected AuthenticationInfo doGetAuthenticationInfo(
AuthenticationToken token) throws AuthenticationException {
String username = (String) token.getPrincipal();
User user = userService.getByUsername(username);
if(user != null) {
AuthenticationInfo authcInfo = new SimpleAuthenticationInfo(user.getUsername(), user.getPassword(), "myRealm");
return authcInfo;
} else {
return null;
}
}
}

这个自定义realm的原理和上一节是一样的,只不过这里使用注入的是service,然后service中使用的是dao接口中的方法去操作数据库。
5. 几个jsp页面
接下来就剩几个jsp页面了,我简单弄一下:
<body>
<form action="${pageContext.request.contextPath }/user/login.do" method="post">
username:<input type="text" name="username"/><br>
password:<input type="password" name="password"/><br>
<input type="submit" value="登陆">${error }
</form>
</body>
<body>
欢迎你${user.username }
<a href="${pageContext.request.contextPath }/user/logout.do">退出</a>
</body>
<body>
认证未通过,或者权限不足
<a href="${pageContext.request.contextPath }/user/logout.do">退出</a>
</body>

6. 测试
根据spring的配置文件中对shiro的url拦截配置,我们首先请求:http://localhost:8080/ShiroSpring/user/admin.do来测试身份认证,然后会跳转到登录页面让我们登陆,登陆成功后,再次请求这个url就会进入success.jsp页面了。
再测试角色和权限认证,可以先后输入http://localhost:8080/ShiroSpring/user/student.do来测试角色认证,输入http://localhost:8080/ShiroSpring/user/teacher.do来测试权限认证。通过登陆不同的用户去测试即可。
