SpringBoot、MyBatis、Shiro、Thymeleaf整合思路

簡單的闡述一下基本的整合思路，方便後面需要用的時候查詢。

1. 建立工程
2. 匯入座標、依賴

<!--        匯入mysql-->
        <dependency>
            <groupId>mysql</groupId>
            <artifactId>mysql-connector-java</artifactId>
        </dependency>
<!--        spring整合mybatis-->
        <dependency>
            <groupId>org.mybatis.spring.boot</groupId>
            <artifactId>mybatis-spring-boot-starter</artifactId>
            <version>2.1.3</version>
        </dependency>
<!--        匯入thymeleaf-->
        <dependency>
            <groupId>org.springframework.boot</groupId>
            <artifactId>spring-boot-starter-thymeleaf</artifactId>
        </dependency>
<!--        匯入shiro-->
        <dependency>
            <groupId>org.apache.shiro</groupId>
            <artifactId>shiro-spring</artifactId>
            <version>1.6.0</version>
        </dependency>
<!--        匯入lombok-->
        <dependency>
            <groupId>org.projectlombok</groupId>
            <artifactId>lombok</artifactId>
            <version>1.16.22</version>
        </dependency>
<!--        thymeleaf整合shiro-->
        <dependency>
            <groupId>org.thymeleaf.extras</groupId>
            <artifactId>thymeleaf-extras-shiro</artifactId>
            <version>2.0.0</version>
        </dependency>

3. 配置
   application.yml
   注意mapper的掃描位置

mybatis:
  mapper-locations: classpath:mapper/*.xml
  type-aliases-package: com.demo.test.pojo

spring:
  datasource:
    username: root
    password: 123456
    url: jdbc:mysql://localhost:3306/test?useUnicode=true&characterEncoding=utf-8&useSSL=true&serverTimezone=UTC
    driver-class-name: com.mysql.cj.jdbc.Driver

4. 建立pojo、dao、mapper、service、serviceimpl、controller

• pojo類的註解有
  @Data ：配置常見的get、set
  @AllArgsConstructor ：帶引數建構函式
  @NoArgsConstructor： 無引數建構函式

• dao介面注意**@Mapper**註解的使用

• mapper檔案的namespace名稱空間只要指向dao介面

• serviceimpl類必須配置**@Service註解，有事務的新增@Transactional**

5. 配置shiro
   自定義類ShiroCofig，新增@Configuration註解
   （倒敘配置比較方便）

• ShiroFilterFactoryBean ：配置攔截
  

• DefaultWebSecurityManager
  

• UserRealm 配置自定義的Realm繼承AuthorizingRealm重寫
  

doGetAuthorizationInfo：授權

 @Override
    protected AuthorizationInfo doGetAuthorizationInfo(PrincipalCollection principalCollection) {
        
        SimpleAuthorizationInfo info=new SimpleAuthorizationInfo();
        //拿到當前登入的物件
        Subject subject = SecurityUtils.getSubject();
        User user = (User)subject.getPrincipal();
        //新增使用者許可權
        info.addStringPermission(user.getPerms());
        return info;
    }

doGetAuthenticationInfo：認證
（可以自行新增鹽制加密）

 @Override
    protected AuthenticationInfo doGetAuthenticationInfo(AuthenticationToken token) throws AuthenticationException {

        UsernamePasswordToken usertoken=(UsernamePasswordToken) token;
        User user = userService.selectUserByName(usertoken.getUsername());
        if (user==null){
            return  null;
        }

        //設定Session
        Subject current = SecurityUtils.getSubject();
        Session session = current.getSession();
        session.setAttribute("USER_SESSION",user);
        return new SimpleAuthenticationInfo(user,user.getPassword(),"");
    }

• ShiroDialect ：用來整合shiro和thymeleaf
  

6. 啟動類
   別忘了@ComponentScan的註解

@SpringBootApplication
@ComponentScan(basePackages = "com.test.**")
public class SpringshiroApplication {

    public static void main(String[] args) {
        SpringApplication.run(SpringshiroApplication.class, args);
    }

}
