Description:

A component required a bean of type 'com.lvjing.dao.DeviceStatusMapper' that could not be found.

Action:

Consider defining a bean of type 'com.lvjing.dao.DeviceStatusMapper' in your configuration.

原错误启动文件 Application.java

package com.lvjing;

/**
 * Created by huanghua on 2017/5/23.
 */

import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.EnableAutoConfiguration;
import org.springframework.boot.autoconfigure.SpringBootApplication;
import org.springframework.boot.autoconfigure.jdbc.DataSourceAutoConfiguration;
import org.springframework.boot.web.servlet.support.SpringBootServletInitializer;

@SpringBootApplication(exclude={DataSourceAutoConfiguration.class})
public class Application extends SpringBootServletInitializer {

    /**启动Spring boot服务**/
    public static void main(String[] args) throws Exception {
        SpringApplication.run(Application.class, args);
    }
}

　　

修改@SpringBootApplication 注解

package com.lvjing;

/**

 */

import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.EnableAutoConfiguration;
import org.springframework.boot.autoconfigure.SpringBootApplication;
import org.springframework.boot.autoconfigure.jdbc.DataSourceAutoConfiguration;
import org.springframework.boot.web.servlet.support.SpringBootServletInitializer;

@SpringBootApplication(exclude={DataSourceAutoConfiguration.class},scanBasePackages = {"com.lvjing.dao.*"})
public class Application extends SpringBootServletInitializer {

    /**启动Spring boot服务**/
    public static void main(String[] args) throws Exception {
        SpringApplication.run(Application.class, args);
    }
}

　　

成功！

2️⃣ 采用注解

@MapperScan("com.lvjing.dao")
