在使用springboot创建新项目后,在启动服务之后报如下错误:

Disconnected from the target VM, address: '127.0.0.1:58647', transport: 'socket'



解决办法:

  1. 检查启动类是否加上如下注解:

  • @MapperScan(basePackages = {"com.xx.xx.mapper"}, markerInterface = BaseMapper.class)
    @ComponentScan(basePackages = {"com.xx.xx"})
    @SpringBootApplication(exclude= {DataSourceAutoConfiguration.class})


2. 检查service的实现类上是否加上了注解 @Service


3. 检查mapper接口类上面是否加了注解:@Mapper


4. 检查pom.xml文件是否有添加了mybatis相关的依赖包,要注意版本兼容问题,同时在pom.xml文件的<build></build>添加如下配置,来保证文件都能正常被扫描到并且加载成功:

<resources>
    <resource>
        <directory>src/main/resources</directory>
        <includes>
            <include>**/*.properties</include>
            <include>**/*.xml</include>
            <include>**/*.json</include>
        </includes>
        <filtering>true</filtering>
    </resource>
</resources>


5. 检查application.properties文件中是否配置了数据库的相关连接信息以及mybatis相关的配置

mybatis.type-aliases-package=com.xx.xx.entity.**
mybatis.mapper-locations=classpath:mapper/*.xml
#mybatis.configuration.log-impl=org.apache.ibatis.logging.stdout.StdOutImpl


如果以上几个步奏都没法解决重启报这个错误的话,那一定是jar包的版本有问题,可以试着降低版本,然后重新加载maven依赖,编译之后重新在试试。
