4、复制实体类文件utils到目录下(没有就创建)
五、创建web项目子模块web-management
1、创建web项目子模块web-management
2、修改pom.xml
核心是引入本文的子模块entity和utils
<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>com.bocai</groupId>

<version>0.0.1-SNAPSHOT</version>
<relativePath>../bocai-parent/pom.xml</relativePath>
</parent>
<artifactId>bocai-web-management</artifactId>
<!-- 1、注释 打包方式(不确定)-->

</properties>
<dependencies>
<!-- 2、 注释 junit -->
<!--
<dependency>
<groupId>junit</groupId>
<artifactId>junit</artifactId>
<version>3.8.1</version>
<scope>test</scope>
</dependency>
-->
<!-- 3、加入 子模块依赖 -->
<dependency>
<groupId>com.bocai</groupId>
<artifactId>bocai-entity</artifactId>
<version>0.0.1-SNAPSHOT</version>
</dependency>
<dependency>

</project>
3、复制web项目文件
部分文件可能会报错,主要体现在 web起步依赖 ,到每个文件单独处理一下
4、新建resources
5、resources新建目录com/bocai/mapper
6、复制相关文件
7、 复制启动程序
package com.bocai;
import lombok.extern.slf4j.Slf4j;
import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
import org.springframework.boot.web.servlet.ServletComponentScan;
@Slf4j
@ServletComponentScan //开启了对servlet组件支持 Filter
@SpringBootApplication
public class AppApplication {
public static void main(String[] args) {
SpringApplication.run(AppApplication.class, args);
log.info("============ 服务启动完成!=====================");
}
}
AppApplicationTests 注释了一个测试代码,打包的时候报错
package com.bocai;
import io.jsonwebtoken.Claims;
import io.jsonwebtoken.Jwts;
import io.jsonwebtoken.SignatureAlgorithm;
import org.junit.jupiter.api.Test;
import org.springframework.boot.test.context.SpringBootTest;
import java.util.Date;
import java.util.HashMap;
import java.util.Map;
@SpringBootTest
class AppApplicationTests {
@Test
void contextLoads() {
}
/**
* 生成Jwt令牌
*/
@Test
public void testGenJwt(){
Map<String, Object> claims = new HashMap<>();
claims.put("id",1);
claims.put("name","bocai");
String jwt = Jwts.builder()
.signWith(SignatureAlgorithm.HS256, "bocai") // 签名算法 算法有哪些上官网
.setClaims(claims) //自定义的内容(载荷)
.setExpiration(new Date(System.currentTimeMillis() + 3600* 1000)) // 设置有效期为1h
.compact();
System.out.println(jwt);
}
/**
* 解析Jwt, parseClaimsJws(换成上面生成的jwt)
*/
// @Test
// public void testPareJwt(){
// Claims claims = Jwts.parser()
// .setSigningKey("bocai") //runa要与前面生成一致
// .parseClaimsJws("eyJhbGciOiJIUzI1NiJ9.eyJuYW1lIjoiYm9jYWkiLCJpZCI6MSwiZXhwIjoxNjk3NTM5MTQzfQ.kh_8USqITQHQvnOpWuF8Z7BB0x_BVhfZvOgF1JMcj8o")
// .getBody();
// System.out.println(claims);
//
// }
}
六、启动服务
1、启动后端AppApplication

2、启动ngnix
3、验证数据
