iBatis 的条件查询

之类以传入ID进行举例

Student.xml 在里面设置一个ID的标志位，设置类型

    <select id="selectAllStudentByid" parameterClass="int" resultClass="Student">
    select * from
    student
    where Id=#id#
    </select>

StudentImpl.java文件，这里将ID给传入进去，

    public List<Student> selStudentByid(int id) {
        List<Student> student  = null;
        try {
            student =  sqlMapClient.queryForList("selectAllStudentByid",id);
        } catch (SQLException e) {
            // TODO Auto-generated catch block
            e.printStackTrace();
        }
        return student;
    }

Test.java测试页面

package cn.test.main;

import java.util.List;

import cn.test.domain.Student;
import cn.test.service.IStudent;
import cn.test.service.StudentImpl;

public class Test {

    /**
     * @param args
     */
    public static void main(String[] args) {
        // TODO Auto-generated method stub
    IStudent istudent2 = new StudentImpl();
    List<Student> student2 = istudent2.selStudentByid(1);
    System.out.printf("id="+student2.get(0).getId() + "name = " +student2.get(0).getName() + "age = " + student2.get(0).getAge());

    }
