构建core模块

1.环境搭建

1.sunrays-common下新建core模块

2.引入依赖，并设置打包常规配置

2.测试使用

1.启动！

1.创建模块

2.引入依赖

<?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"

            <version>1.0</version>
        </dependency>
    </dependencies>

</project>

3.application.yml 配置MySQL和Minio

server:
  port: 8080 # 服务端口
spring:
  # 数据源配置
  datasource:
    driver-class-name: com.mysql.cj.jdbc.Driver
    username: guest
    password: guest
    url: guest
    type: com.alibaba.druid.pool.DruidDataSource # druid连接池
    druid:
      initial-size: 10          # 初始化连接数（适当减少以节省资源）
      min-idle: 10              # 最小空闲连接数
      max-active: 50            # 最大连接数（根据业务需求调整）
      max-wait: 30000           # 获取连接的最大等待时间（30秒）
      timeBetweenEvictionRunsMillis: 60000  # 每60秒检查一次空闲连接
      minEvictableIdleTimeMillis: 300000    # 最小空闲时间5分钟后回收
      testWhileIdle: true       # 检查空闲连接是否可用
      testOnBorrow: true        # 检查从连接池获取的连接是否可用
      removeAbandoned: true     # 启用清理超时连接
      removeAbandonedTimeout: 180  # 连接超时时间180秒
      logAbandoned: true        # 记录被清理的连接日志
# minio配置
minio:
  endpoint: http://guest:9000 # minio服务地址
  accessKey: guest # minio服务的accessKey
  secretKey: guest # minio服务的secretKey

4.创建启动类

package com.sunxiansheng.core;

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

/**
 * Description: 核心启动类
 *
 * @Author sun
 * @Create 2024/11/16 17:34
 * @Version 1.0
 */
@SpringBootApplication
public class CoreApplication {

    public static void main(String[] args) {
        SpringApplication.run(CoreApplication.class, args);
    }
}

5.启动测试

2.common-web-starter

1.目录

2.WebController.java

package com.sunxiansheng.core.web.controller;

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

/**
 * Description: Web控制器
 *
 * @Author sun
 * @Create 2024/11/16 18:58
 * @Version 1.0
 */
@RestController
public class WebController {

    @RequestMapping("/hello")
    public String hello() {
        return "Hello, World!";
    }
}

3.结果

3.common-validation-starter

1.目录

2.Req.java 请求参数，使用JSR303注解

package com.sunxiansheng.core.validation.entity.req;

import lombok.AllArgsConstructor;
import lombok.Data;
import lombok.NoArgsConstructor;

import javax.validation.constraints.NotBlank;
import javax.validation.constraints.NotNull;
import javax.validation.constraints.Past;
import java.io.Serializable;
import java.util.Date;

/**
 * Description: 请求参数
 *
 * @Author sun
 * @Create 2024/11/16 19:03
 * @Version 1.0
 */
@Data
@NoArgsConstructor
@AllArgsConstructor
public class Req implements Serializable {

    private static final long serialVersionUID = 1L;

    @NotNull(message = "ID不能为空")
    private Long id;

    @NotBlank(message = "用户名不能为空")
    private String name;

    @NotNull(message = "生日不能为空")
    @Past(message = "生日必须是过去的日期")
    private Date birthday;
}

3.ValidationController.java 测试校验参数

package com.sunxiansheng.core.validation.controller;

import com.sunxiansheng.core.validation.entity.req.Req;
import org.springframework.web.bind.annotation.RequestBody;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RestController;

import javax.validation.Valid;

/**
 * Description: 控制器
 *
 * @Author sun
 * @Create 2024/11/16 19:04
 * @Version 1.0
 */
@RestController
public class ValidationController {

    /**
     * 参数校验
     *
     * @param req
     * @return
     */
    @RequestMapping("/validation")
    public Boolean validation(@RequestBody @Valid Req req) {
        return true;
    }
}

4.结果

4.common-test-starter

1.目录

2.TestComponent.java

package com.sunxiansheng.core.validation.test;

import org.springframework.stereotype.Component;

/**
 * Description: 测试
 *
 * @Author sun
 * @Create 2024/11/16 19:28
 * @Version 1.0
 */
@Component
public class TestComponent {

    public String test() {
        return "test";
    }
}

3.TestClass.java 测试类

package com.sunxiansheng.test;

import com.sunxiansheng.core.CoreApplication;
import com.sunxiansheng.core.validation.test.TestComponent;
import org.junit.jupiter.api.Test;
import org.springframework.boot.test.context.SpringBootTest;

import javax.annotation.Resource;

/**
 * Description: 测试类
 *
 * @Author sun
 * @Create 2024/11/16 19:24
 * @Version 1.0
 */
@SpringBootTest(classes = CoreApplication.class) // 指定启动类
public class TestClass {

    @Resource
    private TestComponent testComponent;

    @Test
    void test() {
        System.out.println("testComponent.test() = " + testComponent.test());
    }
}

4.结果

5.common-mybatis-plus-starter

1.生成CRUD（注意五个必要字段）

2.生成的代码结构

3.测试

6.common-minio-starter

1.测试Controller
