一、权限管理的实现

服务端的各种资源要被SpringSecurity的权限管理控制可以通过注解和标签两种方式来处理。

放开了相关的注解后在Controller中就可以使用相关的注解来控制了

JSR250注解

/*** JSR250*/
@Controller
@RequestMapping("/user")
public class UserController {@RolesAllowed(value = {"ROLE_ADMIN"})@RequestMapping("/query")public String query(){System.out.println("用户查询....");return "/home.jsp";}@RolesAllowed(value = {"ROLE_USER"})@RequestMapping("/save")public String save(){System.out.println("用户添加....");return "/home.jsp";}@RequestMapping("/update")public String update(){System.out.println("用户更新....");return "/home.jsp";}
}

Spring表达式

/*** Spring表达式*/
@Controller
@RequestMapping("/order")
public class OrderController {@PreAuthorize(value = "hasAnyRole('ROLE_USER')")@RequestMapping("/query")public String query(){System.out.println("用户查询....");return "/home.jsp";}@PreAuthorize(value = "hasAnyRole('ROLE_ADMIN')")@RequestMapping("/save")public String save(){System.out.println("用户添加....");return "/home.jsp";}@RequestMapping("/update")public String update(){System.out.println("用户更新....");return "/home.jsp";}
}

SpringSecurity注解

@Controller
@RequestMapping("/role")
public class RoleController {@Secured(value = "ROLE_USER")@RequestMapping("/query")public String query(){System.out.println("用户查询....");return "/home.jsp";}@Secured("ROLE_ADMIN")@RequestMapping("/save")public String save(){System.out.println("用户添加....");return "/home.jsp";}@RequestMapping("/update")public String update(){System.out.println("用户更新....");return "/home.jsp";}
}

然后在页面模板文件中可以通过taglib来实现权限更细粒度的控制

<%@ page contentType="text/html;charset=UTF-8" language="java" %>
<%@ taglib prefix="security" uri="http://www.springframework.org/security/tags" %>
<html>
<head><title>Title</title>
</head>
<body><h1>HOME页面</h1>
<security:authentication property="principal.username" />
<security:authorize access="hasAnyRole('ROLE_USER')" ><a href="#">用户查询</a><br>
</security:authorize><security:authorize access="hasAnyRole('RO
