Posted 2021-08-15 爱上口袋的天空

1、搭建一个springboot项目

2、导入相应jar包Maven坐标

 完整pom.xml

<?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">

        <artifactId>kgf-java-learning</artifactId>
        <groupId>com.kgf.learning</groupId>
        <version>1.0-SNAPSHOT</version>
        <relativePath>../kgf-java-learning/pom.xml</relativePath>
    </parent>
    <modelVersion>4.0.0</modelVersion>

    <groupId>com.kgf.security</groupId>
    <artifactId>spring-security-demo</artifactId>

    <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>
        <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>
                <version>2.2.11.RELEASE</version>
            </plugin>
            <plugin>
                <artifactId>maven-compiler-plugin</artifactId>
                <configuration>
                    <source>1.8</source>
                    <target>1.8</target>
                </configuration>
            </plugin>
        </plugins>
    </build>
</project>

3、启动类

package com.kgf.security;

import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;

@SpringBootApplication
public class SecurityApplication {

    public static void main(String[] args) {

        SpringApplication.run(SecurityApplication.class,args);

    }

}

4、修改配置文件

5、创建一个hello测试接口

package com.kgf.security.controller;

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

@RequestMapping("test")
@RestController
public class TestController {


    @RequestMapping("hello")
    public String test(){
        return "hello security";
    }
}

6、运行项目

• 访问http://localhost:8081/test/hello，会出现如下的界面：

• 默认的用户名是：user。
• 密码在项目启动的时候会在控制台打印，需要注意的是，每次启动密码都会发生变化。

 

 

输入用户名和密码，就可以访问了:
