Springboot+Shiro+Mybatis+mysql

一 、shiro框架

Shiro是Apache 的一个强大且易用的Java安全框架,执行身份验证、授权、密码学和会话管理。Shiro 主要分为两个部分就是认证和授权两部分

1.Subject代表了当前用户的安全操作

2.SecurityManager：它是Shiro框架的核心，典型的Facade模式，Shiro通过SecurityManager来管理内部组件实例，并通过它来提供安全管理的各种服务。

3.Authenticator即认证器，对用户身份进行认证，Authenticator是一个接口，shiro提供ModularRealmAuthenticator实现类，通过ModularRealmAuthenticator基本上可以满足大多数需求，也可以自定义认证器。

4.Authorizer即授权器，用户通过认证器认证通过，在访问功能时需要通过授权器判断用户是否有此功能的操作权限。

 

5.Realm充当了Shiro与应用安全数据间的“桥梁”或者“连接器”。也就是说，当对用户执行认证（登录）和授权（访问控制）验证时，Shiro会从应用配置的Realm中查找用户及其权限信息。

6.sessionManager即会话管理，shiro框架定义了一套会话管理，它不依赖web容器的session，所以shiro可以使用在非web应用上。

二：引入依赖

二：yml配置:

1.application-dao.yml

# spring整合配置
spring:
  # 数据源配置
  datasource:
    driver-class-name: com.mysql.jdbc.Driver
    url: jdbc:mysql://localhost:3306/weather?useUnicode=true&characterEncoding=utf-8&serverTimezone=UTC
    username: root
    password: root
    # 使用druid连接池，当使用其他连接池的时候，可以指定type类型为对应的数据源
    type: com.alibaba.druid.pool.DruidDataSource
    druid:
      maxActive: 1000
      initialSize: 10
      maxWait: 1000
      minIdle: 10
      timeBetweenEvictionRunsMillis: 60000
      minEvictableIdleTimeMillis: 300000
      validationQuery: select 1
      testWhileIdle: true
      testOnBorrow: false
      testOnReturn: false
      maxPoolPreparedStatementPerConnectionSize: 0
      # 监控
      stat-view-servlet:
        url-pattern: /druid/*
        reset-enable: false
        login-username: admin
        login-password: admin
        allow: 127.0.0.1
      web-stat-filter:
        url-pattern: /*
        exclusions: /druid/*,*.js,*.css,*.html,*.png,*.jpg
# mybatis配置
mybatis:
    type-aliases-package: edu.nf.ch06.entity
    mapper-locations: classpath:/mapper/*.xml
# 分页插件配置
pagehelper:
    # 数据库方言
    helper-dialect: mysql
    # 分页合理化参数，默认值为false。当该参数设置为 true 时，pageNum<=0 时会查询第一页
    reasonable: true
    # 分页参数
    support-methods-arguments: true

2.application-dao.yml

# web容器配置
server:
  # 设置tomcat(如果切换了Jetty，
  # 那么这里换成Jetty的相关配置，并把tomcat的配置注释)
  #tomcat:
  #uri-encoding: UTF-8
  # 指定端口
  port: 8081
  # 指定项目的ContextPath路径,8080后面紧跟着的项目名
  servlet:
    context-path: /ch06
spring:
  # 配置http字符编码过滤器配置（CharacterEncodingFilter）
  http:
    encoding:
      charset: UTF-8
      enabled: true
      force: true
  # jackson日期格式化和时区设置
  jackson:
    date-format: yyyy-MM-dd HH:mm:ss
    time-zone: GMT+8

三：导入数据库(这里用city_name当做用户名,city_code做为密码)

SET FOREIGN_KEY_CHECKS = 1;

四：Controller层

package edu.nf.ch06.controller;

public class CityController extends BaseController{

    @Autowired
    private CityService cityService;

    @GetMapping("/list_city")

    public ResponseVO listCity(){
        List<City> list = cityService.listCity();
        return success(list);
    }
　　
    @RequestMapping("/add")
    public String add(){

    public String test(){
        System.out.println("测试权限");
        return "测试注解RequiresPermissions是否有用";
    }

    @RequestMapping("/index")
    @RequiresRoles(value={"江西"})
    public String index(){
        System.out.println("修改");
        return "江西登入的用户有此权限";
    }

    @RequestMapping("/unAuth")
    public String unAuth(){
        System.out.println("修改");
        return "未经授权，无法访问此页面";

    @RequestMapping("/login")
    public String login(String cityName, String cityCode, Model model){
        Subject subject = SecurityUtils.getSubject();
        UsernamePasswordToken token =  new UsernamePasswordToken(cityName,cityCode);
        try {
            subject.login(token);
            return "登入成功";
        } catch (UnknownAccountException e) {

            model.addAttribute("msg","密码错误");
            return "密码错误";

六:测试

1.通过用户名：江西 登入的用户具有添加没有修改权限

2.通过用户名：广东登入的用户具有修改没有添加权限

3.需要了解更多进入:http://shiro.apache.org/
