Spring security 知识笔记【入门】

一、生成spring boot项目文件

二、pom文件如下

<?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>

    <groupId>com.Eleven</groupId>
    <artifactId>Eleven</artifactId>
    <version>1.0-SNAPSHOT</version>
    <parent>
        <groupId>org.springframework.boot</groupId>
        <artifactId>spring-boot-starter-parent</artifactId>
        <version>2.2.0.M2</version>
        <relativePath/> <!-- lookup parent from repository -->
    </parent>
    <dependencies>
        <dependency>
            <groupId>org.springframework.boot</groupId>
            <artifactId>spring-boot-starter-web</artifactId>
        </dependency>
        <dependency>
            <groupId>org.springframework.boot</groupId>
            <artifactId>spring-boot-starter-security</artifactId>
        </dependency>
    </dependencies>

</project>

 

二、Spring Boot启动文件

package Eleven;

import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
import org.springframework.boot.web.servlet.ServletComponentScan;

@SpringBootApplication
@ServletComponentScan   //扫描过滤器等servlet、filter注解
public class ElevenApplication {
    public static void main(String[] args){
        SpringApplication.run(ElevenApplication.class,args);
    }
}

 

三、新建两个controller

package Eleven.controller;

import org.springframework.web.bind.annotation.GetMapping;
import org.springframework.web.bind.annotation.RestController;




@RestController
public class AuthenticationTestController {
    @GetMapping("/user")
    public String helloWorld(){
        return "This is a user page!";
    }

    @GetMapping("/admin/test/*")
    public String getAdminInfo(){
        return "This is Admin page!";
    }



}

 

四、启动后，访问controller路径，提示需要登录，默认用户user，默认的密码是动态的，已在控制台输出

 

 

五、登录后可显示controller的内容

 

六、自定义用户名、密码

在配置文件（application.properties）中增加以下

spring.security.user.name = admin
spring.security.user.password = 123456
