(三)Shiro整合SSM实践

maven工程的pom文件引入相关的依赖就不赘述了。下面开始过程:
shiro本质还是过滤器所以,
首先在web.xml中进行如下配置:

<filter>
    <filter-name>shiroFilter</filter-name>
    <filter-class>org.springframework.web.filter.DelegatingFilterProxy</filter-class>
    <init-param>
        <param-name>targetFilterLifecycle</param-name>
        <param-value>true</param-value>
    </init-param>
</filter>
<filter-mapping>
    <filter-name>shiroFilter</filter-name>
    <url-pattern>/*</url-pattern>
</filter-mapping>

然后spring-shiro.xml的配置大致如下:

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

	xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:context="http://www.springframework.org/schema/context"

	    <property name="sessionIdCookieEnabled" value="true"/>  
	    <property name="sessionIdCookie" ref="sessionIdCookie"/>  
	</bean> 
	
	
</beans>

注意:如果用shiro的注解,需要在spring-mvc.xml中配置下面:

<!-- 开启shiro注解的支持。 -->
    <aop:config proxy-target-class="true"></aop:config> 
    <bean class="org.apache.shiro.spring.security.interceptor.AuthorizationAttributeSourceAdvisor">
    	<property name="securityManager" ref="securityManager"/>
    </bean>

自定义的Realm类:

public class BugeasyRealm extends AuthorizingRealm {
	
	@Autowired
	private UserService userService;
	
	@Autowired
	private RoleService roleService;

	@Override
	protected AuthorizationInfo doGetAuthorizationInfo(PrincipalCollection principals) {
		
		System.out.println("--------------------------开始授权认证---------------------------------");
		//授权
		String username = (String)principals.getPrimaryPrincipal();

        SimpleAuthorizationInfo authorizationInfo = new SimpleAuthorizationInfo();
        
        Set<String> roles = userService.getUserRoleByName(username);
        authorizationInfo.setRoles(roles);
        
        Set<String> permissions = roleService.getRolePermissionsByRoleIds(username);
        authorizationInfo.setStringPermissions(permissions);
        
        return authorizationInfo;
	}

	@Override
	protected AuthenticationInfo doGetAuthenticationInfo(AuthenticationToken token) throws AuthenticationException {
		
		//身份认证
		String name = (String) token.getPrincipal();
		String password = new String( (char[])token.getCredentials());
		UserBean userBean = new UserBean();
		userBean.setName(name);
		userBean.setPassword(password);
		
		UserBean hasBean = userService.getUserByNameAndPwd(userBean);
		if(hasBean == null){
			throw new UnknownAccountException();//没找到帐号
		}
		AuthenticationInfo info = new SimpleAuthenticationInfo(name,password,"bugeasyRealm");
		return info;
	}

}

service、dao代码暂时省去。

controller代码如下:

@PostMapping(path="/login")
public ModelAndView loginByShiro(HttpServletRequest request, HttpServletResponse response,@ModelAttribute("user") UserBean user){
	ModelAndView mv = new ModelAndView();
	if(user != null){
		Subject subject = SecurityUtils.getSubject();  
	    UsernamePasswordToken token = new UsernamePasswordToken(user.getName(), user.getPassword());
	    try{
	    	subject.login(token);
	    	mv.addObject("user", user);
	    	mv.addObject("userName", user.getName());
	    	
	    	mv.setViewName("/main");
	    }catch(Exception e){
	    	e.printStackTrace();
	    	mv.addObject("errmsg", "登录的用户名/密码错误,请重新登录");
	    	mv.setViewName("/login");
	    }
	    return mv;
	      
	}
	return mv;
}

JSP页面如果使用标签,需要引入:

<%@taglib prefix="shiro" uri="http://shiro.apache.org/tags" %>

这样,就完成了和ssm的整合,项目中就可以使用编程式、注解、JSP标签进行shiro的使用了。
