How do I create an Object in Mybattis (Spring) mapper using select on a table (Spring)

I am new to MyBatis-Spring. I have two SQL tables lets say A list of Universities and a list of Students

UNIVERISTY table has id, name, listOfStudents

STUDENTS table has name_ofStudent, GPA, age, major, id, universityId

I have University.java, Student.java, UniversityManager.java, StudentManager.java (both with crud operations in their manager) (read's parameter is an int id)

if this is my UniversityMapper.xml (Below) How do I "SELECT" (by ID) a University? I know how the basic select works but my main question is once I select get by id the name of the university how do I also so get the list of students belonging to that students. I want to know how to select using mybatis the list of students that match the universityID and create a student object and make it part of the universty object. PLEASE Urgent Help!

    values (#{id,jdbcType=VARCHAR}, #{name,jdbcType=VARCHAR})
        </insert>

   <select id="getUniversity" parameterType="int" resultMap="java.University">
