使用idea创建spring boot工程

勾选web里的web依赖

我们在pom.xml里自己导入shiro的依赖

具体依赖如下:

<?xml version="1.0" encoding="UTF-8"?>
<project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
         xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/xsd/maven-4.0.0.xsd">
    <modelVersion>4.0.0</modelVersion>
    <parent>
        <groupId>org.springframework.boot</groupId>
        <artifactId>spring-boot-starter-parent</artifactId>
        <version>2.1.5.RELEASE</version>
        <relativePath/> <!-- lookup parent from repository -->
    </parent>
    <groupId>com.liy</groupId>
    <artifactId>shiro</artifactId>
    <version>0.0.1-SNAPSHOT</version>
    <name>shiro</name>
    <description>Demo project for Spring Boot</description>

    <properties>
        <java.version>1.8</java.version>
    </properties>

    <dependencies>
        <dependency>
            <groupId>org.springframework.boot</groupId>
            <artifactId>spring-boot-starter-web</artifactId>
        </dependency>
        <dependency>
            <groupId>org.apache.shiro</groupId>
            <artifactId>shiro-web</artifactId>
            <version>1.4.0</version>
        </dependency>
        <dependency>
            <groupId>org.apache.shiro</groupId>
            <artifactId>shiro-spring</artifactId>
            <version>1.4.0</version>
        </dependency>

        <dependency>
            <groupId>org.springframework.boot</groupId>
            <artifactId>spring-boot-starter-test</artifactId>
            <scope>test</scope>
        </dependency>
    </dependencies>

    <build>
        <plugins>
            <plugin>
                <groupId>org.springframework.boot</groupId>
                <artifactId>spring-boot-maven-plugin</artifactId>
            </plugin>
        </plugins>
    </build>

</project>

然后我们写个自定义realm类 , 去验证一下就行了 ,我们这要测试shiro使用成功就行了 ,就进行下验证就行了

MyRealm

package com.liy.realm;

import org.apache.shiro.authc.*;
import org.apache.shiro.authz.AuthorizationInfo;
import org.apache.shiro.realm.AuthorizingRealm;
import org.apache.shiro.subject.PrincipalCollection;

public class MyRealm extends AuthorizingRealm {
    @Override
    protected AuthorizationInfo doGetAuthorizationInfo(PrincipalCollection principals) {
        return null;
    }

    @Override
    protected AuthenticationInfo doGetAuthenticationInfo(AuthenticationToken token) throws AuthenticationException {
        String principal = (String) token.getPrincipal();
        if (!"liy".equals(principal)){
            throw new UnknownAccountException("账号不存在");
        }

        return new SimpleAuthenticationInfo(principal,"123",getName());
    }
}

原先在ssm框架里整合shiro是在spring配置文件中去配置 ,而现在我们在spring boot中就写个shiro的配置类 ,

把原先要在spring容器里配置的shiro所需要的bean ,在shiro配置类配置即可

ShiroConfig

package com.liy;

import com.liy.realm.MyRealm;
import org.apache.shiro.mgt.SecurityManager;
import org.apache.shiro.spring.web.ShiroFilterFactoryBean;
import org.apache.shiro.web.mgt.DefaultWebSecurityManager;
import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;

import java.util.LinkedHashMap;
import java.util.Map;

@Configuration
public class ShiroConfig {
    @Bean
    MyRealm myRealm(){
        return  new MyRealm();
    }

    @Bean
    SecurityManager securityManager(){
        DefaultWebSecurityManager manager = new DefaultWebSecurityManager();
        manager.setRealm(myRealm());
        return manager;
    }

    @Bean
    ShiroFilterFactoryBean shiroFilterFactoryBean(){
        ShiroFilterFactoryBean bean = new ShiroFilterFactoryBean();
        bean.setSecurityManager(securityManager());
        bean.setLoginUrl("/login");
        bean.setSuccessUrl("/index");
        bean.setUnauthorizedUrl("/unauthorized");

        Map<String, String> map = new LinkedHashMap<>();
        map.put("/doLogin","anon");
        map.put("/**","authc");
        bean.setFilterChainDefinitionMap(map);
        return bean;
    }
}

然后写个controller类定义几个基本的请求接口

package com.liy.controller;

import org.apache.shiro.SecurityUtils;
import org.apache.shiro.authc.AuthenticationException;
import org.apache.shiro.authc.UsernamePasswordToken;
import org.apache.shiro.subject.Subject;
import org.springframework.web.bind.annotation.GetMapping;
import org.springframework.web.bind.annotation.PostMapping;
import org.springframework.web.bind.annotation.RestController;

@RestController
public class HelloController {

    @GetMapping("/hello")
    public String hello(){
        return "hello";
    }


    @PostMapping("/doLogin")
    public void doLogin(String name ,String password){
        Subject subject = SecurityUtils.getSubject();
        try {
            subject.login(new UsernamePasswordToken(name,password));
            System.out.println("登陆成功");
        }catch (AuthenticationException e){

            System.out.println("登陆失败");
        }

    }

    @GetMapping("/login")
    public String login(){
        return "please login";
    }

}

然后你可以测试先不登录 ,直接请求去访问 /hello  ,看看会不会被跳到 /login里, 看到/login返回的"please login"  让你去登陆

然后去访问 /doLogin  去输入name = liy  , password=123 ,登陆后,看看后台控制台是否打印登陆成功

记得这里是post请求

使用postman这个浏览器插件 ,可以发送不同的请求方式
