SpringBoot整合shiro环境搭建

1）在原来的项目基础上，新建一个springboot模块

2）导入thymeleaf依赖：


<!--thymeleaf-->
<dependency>
    <groupId>org.springframework.boot</groupId>
    <artifactId>spring-boot-starter-thymeleaf</artifactId>
</dependency>

3）测试保证环境没问题：

index.html

<!DOCTYPE html>
<html lang="en" xmlns:th="http://www.thymeleaf.org">
<head>
    <meta charset="UTF-8">
    <title>首页</title>
</head>
<body>

<h1>首页</h1>

<p th:text="${msg}"></p>

</body>
</html>

MyController:

@Controller
public class MyController {

    //跳转到首页
    @RequestMapping({"/", "/index","index.html"})
    public String toIndex(Model model){
        model.addAttribute("msg","Hello!Shiro!");
        return "index";
    }

}

4）整合shiro

1.导入shiro整合spring的包

        <!--shiro整合spring的包-->
        <dependency>
            <groupId>org.apache.shiro</groupId>
            <artifactId>shiro-spring</artifactId>
            <version>1.8.0</version>
        </dependency>

3.配置Shiro

ShiroConfig:

@Configuration
public class ShiroConfig {

    //ShiroFilterFactoryBean
    @Bean
    public ShiroFilterFactoryBean getShiroFilterFactoryBean(@Qualifier("dwsm") DefaultWebSecurityManager sm){
        ShiroFilterFactoryBean bean = new ShiroFilterFactoryBean();
        //设置安全管理器
        bean.setSecurityManager(sm);
        return bean;
    }


    //DefaultWebSecurityManager
    //@Qualifier("userRealm") UserRealm userRealm这里的意思是：使得这里的userRealm与spring容器中的beanid="userRealm"的bean对象绑定
    @Bean(name = "dwsm") //这里加上(name = "dwsm")之后，组件名就由原来的getDefaultWebSecurityManager变为dwsm
    public DefaultWebSecurityManager getDefaultWebSecurityManager(@Qualifier("userRealm") UserRealm userRealm){
        DefaultWebSecurityManager securityManager = new DefaultWebSecurityManager();
        //关联UserRealm
        securityManager.setRealm(userRealm);
        return securityManager;
    }

    //创建 realm 对象  需要自定义一个类UserRealm
    //这里的@Bean是给spring容器添加组件，并且返回类型UserRealm即为组件类型，该组件的id=“userRealm”即方法名
    @Bean
    public UserRealm userRealm(){
        return new UserRealm();
    }

}

自定义一个UserRealm继承AuthorizingRealm

//自定义的realm
public class UserRealm extends AuthorizingRealm {

    //授权
    @Override
    protected AuthorizationInfo doGetAuthorizationInfo(PrincipalCollection principalCollection) {
        System.out.println("执行了授权doGetAuthorizationInf");
        return null;
    }

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

4.前端页面

add.html:

<h1>add</h1>

update.html:

<h1>update</h1>

index.html:

<h1>首页</h1>

<p th:text="${msg}"></p>

<a th:href="@{/user/add}">add</a>
<a th:href="@{/user/update}">update</a>

5.MyController:

@Controller
public class MyController {

    //跳转到首页
    @RequestMapping({"/", "/index","index.html"})
    public String toIndex(Model model){
        model.addAttribute("msg","Hello!Shiro!");
        return "index";
    }

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


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

}
