QUESTION

Mybatis custom type handler doesn't work: java.lang.NoSuchMethodException: org.springframework.security.core.GrantedAuthority.&lt;init&gt;()

Asked 2021-Jun-14 at 07:50

** I am implementing role-based access control to my application. There are 3 users(Admin, Teacher, Student) in the application with same attribute so I created a basedUser entity to let them inherit it. I wished to get the user's authority when I select it from the database, so I created a type handler to convert the authority in String type to GrantedAuthority type in the process but I don't know why I keep getting this error: **

nested exception is org.mybatis.spring.MyBatisSystemException: nested exception is org.apache.ibatis.reflection.ReflectionException: Error instantiating interface org.springframework.security.core.GrantedAuthority with invalid types () or values (). Cause: java.lang.NoSuchMethodException: org.springframework.security.core.GrantedAuthority.()] with root cause

I have been looking for answers to this problem but not getting anywhere close, does anyone know how to solve this problem??

ANSWER

Answered 2021-Jun-14 at 07:50

Type handler is not a good fit for your usage.
You should use constructor mapping.

...
<collection property="authorities" 
  ofType="org.springframework.security.core.authority.SimpleGrantedAuthority">
  <constructor>
    <idArg column="authority" javaType="string" />
  </constructor>
</collection>
...

As GrantedAuthority is an interface and MyBatis does not know how to instantiate it, you need to specify a concrete type (i.e. SimpleGrantedAuthority) for the ofType.
