mybatis framework - using resultMap for advanced mapping results, use collection of property

Requirements: Gets the user's user information and address lists  

Modify user entity class to add a reference collection.

/ **
* eradicate user id, get the address information in this role
* @param userID
* @return
* /
public the User getUserListAddressByUserID (@Param ( "userID") Integer userID);

 

<The resultMap type = "the User" ID = "userAddressList">
<ID Property = "ID" column = "ID" />
<Result Property = "userCode" column = "userCode" />
<Result Property = "the userName" column = "the userName" />
<Property result = "userRole" column = "userRole" />
<-! List collection class User class referenced in order to reuse the same, the results may be mapped using resultMap collection elements mentioned outside, and the association of this usage is the same ->
<= Collection Property "as addressList" ofType = "the Address" >
<Property ID = "ID" column = "B_ID" />
<Property Result = "Contact" column = "Contact" />
<Property Result = "addressDesc" column = "addressDesc" />
<result property="tel" column="tel" />
</collection>
</resultMap>
<select id="getUserListAddressByUserID" resultMap="userAddressList" parameterType="Integer">
SELECT a.*,b.id as b_id,b.contact,b.addressdesc,b.tel from smbms_user a,smbms_address b where a.id=b.userid and a.id=#{userID}
