Failed to execute goal org.apach

错误信息：

Failed to execute goal org.apache.maven.plugins:maven-surefire-plugin:2.22.2:test (default-test) on project web-class-book: There are test failures.

Please refer to D:\idea_workspace\web-class-book\target\surefire-reports for the individual test results.

Please refer to dump files (if any exist) [date].dump, [date]-jvmRun[N].dump and [date].dumpstream.

原因：

UserMapper.java配置了@Select，但UserMapper.xml也配置了<Select>导致的。

两个地方的代码重复了。取其一即可。

```

@Mapper

public interface UserMapper {

@Select("select * from user")

public List list();

}

```

```

<select id="list" resultType="com.demo.User">

    select* from user;

</select>

```
