Mybatis one-to-many fuzzy query multi-table multi-field query

Project scene:

Tip: Here is a brief description of the project related background:
for example: project scenario: example: resource application table (main table), resource table (secondary table). One-to-many relationship

---

Problem Description:

Tips: Here is a description of the problems encountered in the project:
For example, the front desk uses advanced search to fuzzy query multiple values, there are values ​​in the main table and values ​​in the secondary table.
Code for receiving data in APP:

@Override
        public void run() {
    
    
            bytes = mmInStream.read(buffer);
            mHandler.obtainMessage(READ_DATA, bytes, -1, buffer).sendToTarget();
        }

---

Cause Analysis:

Tip: Fill in the analysis of the problem here:
For example, there is a way to get the xml in the main table. The keyWrod (keyword) of the keyword query is used. The collection tag in mybatis is used. Multiple values ​​can be passed in the subquery column when called, but The source of the column value is the parameter returned by the sql statement, that is, the header in the sql, and the value is taken. The keyWrod is just a temporary variable defined by the front end and me, and it needs to be passed to the query method in the xml called by the payment table through the column attribute.

solution:

Tip: Fill in the specific solution to the problem here:
For example: Use the characteristics of mysql to convert the entered value into a new column. Then get it out of the returned parameters.

Ordinary query: query

that returns the input value:
