SpringBoot+Shiro环境搭建

继上篇之后入门

搭建环境

依赖

    <!--需要导入shiro的spring的整合包-->
    <dependency>
        <groupId>org.apache.shiro</groupId>
        <artifactId>shiro-spring</artifactId>
        <version>1.4.1</version>
    </dependency>
    <!--thymeleaf模板-->
    <dependency>
        <groupId>org.thymeleaf</groupId>
        <artifactId>thymeleaf-spring5</artifactId>
    </dependency>
    <dependency>
        <groupId>org.thymeleaf.extras</groupId>
        <artifactId>thymeleaf-extras-java8time</artifactId>
    </dependency>
    <dependency>
        <groupId>org.springframework.boot</groupId>
        <artifactId>spring-boot-starter-web</artifactId>
    </dependency>

新建一个config包

包下新建一个ShiroConfig类

这个类的顺序是从下往上写 ，下类写完，上类需要就调用它

@Configuration
public class ShiroConfig {

    //ShiroFilterFactoryBean 过滤对象
    @Bean
    public ShiroFilterFactoryBean getShiroFilterFactoryBean(@Qualifier("securityManager") DefaultWebSecurityManager defaultWebSecurityManager){
        ShiroFilterFactoryBean bean = new ShiroFilterFactoryBean();
        //设置安全管理器
        bean.setSecurityManager(defaultWebSecurityManager);

        return bean;
    }

    //DefaultWebSecurityManager 安全对象
    @Bean(name = "securityManager")
    public DefaultWebSecurityManager defaultWebSecurityManager(@Qualifier("userRealm") UserRealm userRealm){
        DefaultWebSecurityManager securityManager = new DefaultWebSecurityManager();
        //关联userRealm
        securityManager.setRealm(userRealm);
        return securityManager;
    }

    //创建realm对象，需要自定义  先有这一步 因为 DefaultWebSecurityManager 需要这个
    @Bean
    public UserRealm userRealm(){
        return new UserRealm();
    }
}

新建一个UserRealm

//自定义的UserRealm    需要 继承extends AuthorizingRealm
public class UserRealm extends AuthorizingRealm {

    @Autowired
    UserService userService;
    //授权
    @Override
    protected AuthorizationInfo doGetAuthorizationInfo(PrincipalCollection principalCollection) {
        System.out.println("执行了=>授权doGetAuthorizationInfo");
        return null;
    }

    //认证
    @Override
    protected AuthenticationInfo doGetAuthenticationInfo(AuthenticationToken token) throws AuthenticationException {
        System.out.println("执行了=>认证doGetAuthenticationInfo");
        return null;
    }
}

编写拦截页面

在resources下的templates包下新建一个user包，在user新建两个html页面：分别为 add.html,update.html
resources > templates > user > add.html,update.html

add和update内容可以写add和update标识一下

写index.html

add update

编写Controller

@Controller
public class MyController {
    @RequestMapping({"/","/index"})
    public String toIndex(Model model){
        model.addAttribute("msg","hello");
        return "index";
    }

    @RequestMapping("/user/add")
    public String add(){
        return "user/add";
    }

    @RequestMapping("/user/update")
    public String update(){
        return "user/update";
    }
}
