SSM权限操作

• 创建数据库
• 创建用户信息表

-- 用户表
CREATE TABLE users(
id varchar2(32) default SYS_GUID() PRIMARY KEY,
email VARCHAR2(50) UNIQUE NOT NULL,
username VARCHAR2(50),
PASSWORD VARCHAR2(50),
phoneNum VARCHAR2(20),
STATUS INT
)

• 编写实体类

package org.hacker.ssm.domain;

/**
 * @author HackerStar
 * @create 2020-04-24 11:09
 */
public class UserInfo {
    private String id;
    private String username;
    private String email;
    private String password;
    private String phoneNum;
    private int status;
    private String statusStr;
    private List<Role> roles;

    public String getId() {
        return id;
    }

    public void setId(String id) {
        this.id = id;
    }

    public String getUsername() {
        return username;
    }

    public void setUsername(String username) {
        this.username = username;
    }

    public String getEmail() {
        return email;
    }

    public void setEmail(String email) {
        this.email = email;
    }

    public String getPassword() {
        return password;
    }

    public void setPassword(String password) {
        this.password = password;
    }

    public String getPhoneNum() {
        return phoneNum;
    }

    public void setPhoneNum(String phoneNum) {
        this.phoneNum = phoneNum;
    }

    public int getStatus() {
        return status;
    }

    public void setStatus(int status) {
        this.status = status;
    }

    public String getStatusStr() {
        return statusStr;
    }

    public void setStatusStr(String statusStr) {
        this.statusStr = statusStr;
    }

    public List<Role> getRoles() {
        return roles;
    }

    public void setRoles(List<Role> roles) {
        this.roles = roles;
    }
}

• 创建角色表

CREATE TABLE role(
id varchar2(32) default SYS_GUID() PRIMARY KEY,
roleName VARCHAR2(50),
roleDescVARCHAR2(50)
)

• 编写实体类

package org.hacker.ssm.domain;

import java.util.List;

/**
 * @author HackerStar
 * @create 2020-04-24 11:12
 */
public class Role {
    private String id;
    private String roleName;
    private String roleDesc;
    private List<Permission> permissions;
    private List<UserInfo> users;

    public String getId() {
        return id;
    }

    public void setId(String id) {
        this.id = id;
    }

    public String getRoleName() {
        return roleName;
    }

    public void setRoleName(String roleName) {
        this.roleName = roleName;
    }

    public String getRoleDesc() {
        return roleDesc;
    }

    public void setRoleDesc(String roleDesc) {
        this.roleDesc = roleDesc;
    }

    public List<Permission> getPermissions() {
        return permissions;
    }

    public void setPermissions(List<Permission> permissions) {
        this.permissions = permissions;
    }

    public List<User> getUsers() {
        return users;
    }

    public void setUsers(List<User> users) {
        this.users = users;
    }
}

• 创建角色-用户中间表

-- 用户角色关联表
CREATE TABLE users_role(
userId varchar2(32),
roleId varchar2(32),
PRIMARY KEY(userId,roleId),
FOREIGN KEY (userId) REFERENCES users(id),
FOREIGN KEY (roleId) REFERENCES role(id)
)

• 创建资源表

CREATE TABLE permission(
id varchar2(32) default SYS_GUID() PRIMARY KEY,
permissionName VARCHAR2(50),
url VARCHAR2(50)
)

• 编写实体类

package org.hacker.ssm.domain;

import java.util.List;

/**
 * @author HackerStar
 * @create 2020-04-24 11:17
 */
public class Permission {
    private String id;
    private String permissionName;
    private String url;
    private List<Role> roles;

    public String getId() {
        return id;
    }

    public void setId(String id) {
        this.id = id;
    }

    public String getPermissionName() {
        return permissionName;
    }

    public void setPermissionName(String permissionName) {
        this.permissionName = permissionName;
    }

    public String getUrl() {
        return url;
    }

    public void setUrl(String url) {
        this.url = url;
    }

    public List<Role> getRoles() {
        return roles;
    }

    public void setRoles(List<Role> roles) {
        this.roles = roles;
    }
}

• 创建权限-角色表

-- 角色权限关联表
CREATE TABLE role_permission(
permissionId varchar2(32),
roleId varchar2(32),
PRIMARY KEY(permissionId,roleId),
FOREIGN KEY (permissionId) REFERENCES permission(id),
FOREIGN KEY (roleId) REFERENCES role(id)
)

Spring Security概述

Spring Security 是 Spring 项目组中用来提供安全认证服务的框架。Spring Security 为基于J2EE企业应用软件提供了全面安全服务。特别是使用领先的J2EE解决方案-Spring框架开发的企业软件项目。

• 如何使用

1. 导入依赖到总工程的pom文件中

<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>

    <!-- 配置加密类 -->
    <bean id="passwordEncoder" class="org.springframework.security.crypto.bcrypt.BCryptPasswordEncoder"/>
</beans>

• 导入登录和登陆失败页面
• 编写service接口及其实现类
• 编写dao接口

package org.hacker.ssm.service;

import org.springframework.security.core.userdetails.UserDetailsService;

/**
 * @author HackerStar
 * @create 2020-04-24 11:34
 */
public interface IUserService extends UserDetailsService {
}

package org.hacker.ssm.service.impl;

import org.hacker.ssm.domain.Role;
import org.hacker.ssm.domain.UserInfo;
import org.hacker.ssm.service.IUserService;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.security.core.authority.SimpleGrantedAuthority;
import org.springframework.security.core.userdetails.User;
import org.springframework.security.core.userdetails.UserDetails;
import org.springframework.security.core.userdetails.UsernameNotFoundException;
import org.springframework.stereotype.Service;
import org.springframework.transaction.annotation.Transactional;

import java.util.ArrayList;
import java.util.List;

/**
 * @author HackerStar
 * @create 2020-04-24 11:34
 */
@Service("userService")
@Transactional
public class UserServiceImpl implements IUserService {

    @Autowired
    private IUserDao userDao;

    @Override
    public UserDetails loadUserByUsername(String username) throws UsernameNotFoundException {
        UserInfo userInfo = userDao.findByUsername(username);
        List<Role> roles = userInfo.getRoles();
        //处理自己的用户对象封装成UserDetails
        User user = new User(userInfo.getUsername(), "{noop}" + userInfo.getPassword(), userInfo.getStatus() == 0 ? false : true, true, true, true, getAuthority(userInfo.getRoles()));
        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;
    }
}

• 实现用户退出功能
  
  在spring-security配置文件中配置

<security:logout invalidate-session="true" logut-url="/logout.do" logout-sucess-url="/login.jsp"/>

• 实现用户查询功能
• 导入页面user-list
• 编写controller模块

package org.hacker.ssm.controller;

import org.hacker.ssm.domain.UserInfo;
import org.hacker.ssm.service.IUserService;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.web.servlet.ModelAndView;

import java.util.List;

/**
 * @author HackerStar
 * @create 2020-04-24 11:55
 */
public class UserController {
    @Autowired
    private IUserService userService;

    public ModelAndView findAll() {
        ModelAndView mv = new ModelAndView();
        List<UserInfo> userList = userService.findAll();
        mv.addObject("userlist", userList);
        mv.setViewName("user-list");
        return mv;
    }
}

• 添加代码到service接口及其实现类

package org.hacker.ssm.service;

import org.hacker.ssm.domain.UserInfo;
import org.springframework.security.core.userdetails.UserDetailsService;

import java.util.List;

/**
 * @author HackerStar

        UserInfo userInfo = null;
        try {
            userInfo = userDao.findByUsername(username);
        } catch (Exception e) {
            e.printStackTrace();
        }
        List<Role> roles = userInfo.getRoles();
        //处理自己的用户对象封装成UserDetails
        User user = new User(userInfo.getUsername(), "{noop}" + userInfo.getPassword(), userInfo.getStatus() == 0 ? false : true, true, true, true, getAuthority(userInfo.getRoles()));
        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;
    }

    @Override
    public List<UserInfo> findAll() {
        return userDao.findAll();
    }
}

• 添加代码到dao接口

package org.hacker.ssm.dao;

        import org.apache.ibatis.annotations.Many;
        import org.apache.ibatis.annotations.Result;
        import org.apache.ibatis.annotations.Results;
        import org.apache.ibatis.annotations.Select;
        import org.hacker.ssm.domain.UserInfo;
        import org.springframework.stereotype.Service;

        import java.util.List;

/**
 * @author HackerStar
 * @create 2020-04-24 11:41
 */
public interface IUserDao {
    @Select("select * from users where username=#{username}")
    @Results({
            @Result(property = "roles",column = "id",javaType = java.util.List.class,many = @Many(select = "com.itheima.ssm.dao.IRoleDao.findRoleByUserId"))
    })
    public UserInfo findByUsername(String username) throws Exception;

    @Select("select * from users")
    List<UserInfo> findAll();
}
