MyBatis Parameter Not Found

I'm triying to calling a rest application but I get a 500 error. The problem maybe be on the MyBatis call but still can't fix it.

This is where I call the execution of MyBatis

@Override
public List<IdentitatBDTO> searchIdentitatsRepresentantsByRelacioIdentitatRepresentat(final String representatIdentificador, final Date dateFi) {

    List<Identitat> identitats = myBatisTemplate.execute(RelacioDao.class, new MyBatisDaoCallback<List<Identitat>>() {
        @Override
        public List<Identitat> execute(MyBatisDao dao) {
            return ((RelacioDao) dao).searchIdentitatsRepresentantsByRelacioIdentitatRepresentat(representatIdentificador, dateFi);
        }
    });

The error that I'm getting is

{
"errorUrl": 
 "http://localhost:8080/idjrepresentaciorest/rest/representacio/representants/12340002L",

But I debugged and saw that the variable that appears to be the problem is filled correctly so why is MyBatis not founding the variable?

Solution

  • @Param annotation has two, one belongs to spring, one belongs to mybatis.Their usage is different.

    • org.springframework.data.repository.query.Param 
      User getUserById(@Param("id") Integer id);
<select id="getUserById" resultMap="userMap">
    select name,age
    from user
    where id=#{0, jdbcType=INTEGER}
<select/>
      It's based on the order of the parameters, and starts from 0.
    • org.apache.ibatis.annotations.Param 
      User getUserById(@Param("id") Integer id);
<select id="getUserById" resultMap="userMap">
    select name,age
    from user
    where id=#{id, jdbcType=INTEGER}
<select/>
      Is based on the parameter name.

    So, check that the annotations you introduced in mapper.java are consistent with the usage in mapper.xml.
