Lemiao-Common-Spring-Boot，一个开箱即用的基础应用配置起步依赖项目

• 默认开启使用 HttpClient 作为 RestTemplate 连接工具，支持配置 Http 连接池参数
• 默认开启配置异步线程池，支持配置线程池参数
• 默认开启 DingDingClient 配置
• 支持开启 Leaf Api，支持获取雪花算法ID、号段ID，支持注解使用 Mybatis Plus 生成ID
• 支持开启应用启动通知多个钉钉群机器人消息
• 未完待续

使用方式

1. 使用 RestTemplate

public class RestTemplateTest {

    @Autowired
    private RestTemplate restTemplate;

    @Test
    public void testRestTemplate() {
        // 
    }

}

2. 使用 DingDingClient

public class DingDingClientTest {

    @Autowired
    private DingDingClient dingDingClient;

    @Test
    public void testRestTemplate() {
        // 
    }

}

3. @Async异步方法实现

public interface HelloService {

    /**
     * 异步sayHello
     *
     * @param name caller name
     */
    void sayHelloAsync(String name);

}

public class HelloServiceImpl implements HelloService {

    /**
     * 异步sayHello
     *
     * @param name caller name
     */
    @Async(value = "threadPool")
    @Override
    public void sayHelloAsync(String name) {
        try {
            TimeUnit.SECONDS.sleep(4);
        } catch (InterruptedException e) {
            log.error("say hello exception", e);
        }
        log.info("service say hello " + name + "!");
    }

}

4. 获取异步线程池

public class ExecutorTest {

    /**
     * 注入异步线程池
     */
    @Resource(name = "threadPool")
    private Executor executor;

    @Test
    public void testExecute() {
        // 
    }

}

5. 手动获取 Leaf Id

public class LeafApiTest {

    @Autowired
    private LeafApi leafApi;

    /**
     * 获取Leaf号段ID
     */
    @Test
    public void testGetSegmentId() {
        Long id = leafApi.getSegmentId("bizKey");
        System.out.println(id);
    }

    /**
     * 获取Leaf雪花算法ID
     */
    @Test
    public void testGetSnowflakeId() {
        Long id = leafApi.getSnowflakeId("bizKey");
        System.out.println(id);
    }

}

6. Mybatis-Plus项目，使用注解方式自动获取 Leaf Id

/**
 * 获取Leaf号段ID
 */
@LeafId(key = "bizKey", idType = LeafIdType.SEGMENT)
public class Entity implements Serializable {

    @ApiModelProperty(value = "主键")
    @TableId(value = "id", type = IdType.ASSIGN_ID)
    private Long id;

}

/**
 * 获取Leaf雪花算法ID
 */
@LeafId(key = "bizKey", idType = LeafIdType.SNOWFLAKE)
public class Entity implements Serializable {

    @ApiModelProperty(value = "主键")
    @TableId(value = "id", type = IdType.ASSIGN_ID)
    private Long id;

}
