how can I get the generated key of an insert with MyBatis? I read many pages about this question but I'm still blocked, could anyone help me, please? This is my code:
The table:
ID_ERROR long primary key
DATE timestamp
TYPE varchar
MESSAGE varchar
SOURCE varchar
The dao:
Long returnedId = 0L;
MyMapper myMapper = this.sqlSession.getMapper(MyMapper.class);
myMapper.insertRecord(returnedId, Utils.now(), t.getClass().getName(), t.getMessage(), c.getName());
return returnedId;
The mapper.java:
public void insertRecord(@Param("returnedId") Long returnedId, @Param("timestamp")Timestamp timestamp,@Param("type") String type,@Param("message") String message,@Param("source") String source);
The mapper.xml
<insert id="insertRecord" parameterType="map" useGeneratedKeys="true" keyProperty="ID_ERROR">
INSERT INTO errors (
DATE,
TYPE,
MESSAGE,
SOURCE
)
VALUES (
#{timestamp},
#{type},
#{message},
#{source}
)
<selectKey resultType="long" order="AFTER" keyProperty="returnedId">
SELECT LAST_INSERT_ID() as returnedId
</selectKey>
</insert>
What is wrong? How can I get the generated key of this insert? Thanks!
For me it is working like this (mybatis 3.x) .. The id must be set auto increment in mysql table
<insert id="createEmpty" parameterType="Project" useGeneratedKeys="true" keyProperty="project.projectId" keyColumn="PROJECT_ID">
INSERT INTO PROJECT (TITLE,DESCRIPTION)
VALUES
(#{title},#{description})
</insert>
NOTE keyProperty="project.projectId"
and useGeneratedKeys="true"
my interface is:
public int createEmpty(@Param("project") Project project, @Param("title") String title,
@Param("description") String description);
finally to get the value (that will be automatically assigned to the pojo's id property) i use:
projectRepository.createEmpty(p, "one", "two");
System.err.print(p.getProjectId() + "\n");
