1、排查Mapper是否正确
@Mapper
public interface TableMapper extends BaseMapper<Table>{
}
2、检查Mybatis-Plus的yml配置
mybatis-plus:
mapper-locations: classpath*:mybatis/mapper/*.xml
type-aliases-package: com.grgbanking.metadatamanage.model.pojo
configuration:
map-underscore-to-camel-case: true
use-generated-keys: true
config-location: classpath*:mybatis/mybatis-config.xml
3、检查pom.xml
<dependency>
<groupId>com.baomidou</groupId>
<artifactId>mybatis-plus-boot-starter</artifactId>
<version>3.1.2</version>
</dependency>
<dependency>
<groupId>com.baomidou</groupId>
<artifactId>mybatis-plus-annotation</artifactId>
<version>3.1.2</version>
</dependency>
<dependency>
<groupId>com.baomidou</groupId>
<artifactId>mybatis-plus-extension</artifactId>
<version>3.1.2</version>
</dependency>
4、检查POJO,会不会遗漏这两个注解 @TableName @TableId
@Data
@EqualsAndHashCode(callSuper = false)
@Accessors(chain = true)
@TableName("t_table")
public class Table {
/**
* 主键
*/
@TableId(value = "id",type = IdType.AUTO)
private Long id;
}
