ibatis 批量查询 注解方式 多参数(多字段)

1     //@Select("select id, student_id, test_paper_problem_id, score, respondence, mistake_id from T_RESPONDENCE where student_id in #{studentId} and test_paper_problem_id=#{testPaperProblemId}")
    @SelectProvider(type = RespondenceBeanProvider.class, method = "getRespondenceBeanByStudentIdANDTestPaperProblemIdBatch")
    @Results(value = {@Result(property = "id", column = "id"), @Result(property = "studentId", column = "student_id"),
            @Result(property = "testPaperProblemId", column = "test_paper_problem_id"),
            @Result(property = "score", column = "score"), @Result(property = "respondence", column = "respondence"),
            @Result(property = "mistakeId", column = "mistake_id")})
    List<RespondenceBean> getRespondenceBeanByStudentIdANDTestPaperProblemIdBatch(List<Set<String>> studentIds);

上面这个代码是mapper   可以理解成dao

package cn.edu.njfu.cs.eas.db.provider;

import java.util.List;
import java.util.Map;
import java.util.Set;

import org.apache.commons.lang.StringUtils;

/**19  * 
 * @author  chenxiaguang@gmail.com
 * @version  [版本号, 2012-9-28]24  */
public class RespondenceBeanProvider
{
    
    public String getRespondenceBeanByStudentIdANDTestPaperProblemIdBatch(Map map)
    {

        /**
         * param1-->studentIds
         * param2-->problemIds
         */
        System.out.println("---" + map);
        List<Set<String>> studentIdsAndProblems = (List<Set<String>>)map.get("list");
//        List<String> problemIds = (List<String>)map.get("param2");

        String studentIdsStr = StringUtils.join(studentIdsAndProblems.get(0), ',');
        String problemIdsStr = StringUtils.join(studentIdsAndProblems.get(1), ',');
        return "select * from T_RESPONDENCE where student_id in (" + studentIdsStr + ") and test_paper_problem_id in ("
                + problemIdsStr + ")";
//        return "select * from T_RESPONDENCE where student_id in (540) and test_paper_problem_id in (31)";
    }
}

上面这个 是provider  为mapper准备

package cn.edu.njfu.cs.eas.db.mapper;

import java.util.ArrayList;
import java.util.HashSet;
import java.util.List;
import java.util.Set;

import org.junit.Before;
import org.junit.Test;

import cn.edu.njfu.cs.eas.common.bean.RespondenceBean;
import cn.edu.njfu.cs.eas.common.util.SpringUtils;

/**24  * 
 * @author  chenxiaguang@gmail.com
 * @version  [版本号, 2012-9-28]29  */
public class RespondenceBeanMapperTest
{
    
    private RespondenceBeanMapper mapper;

    /**36      * 
     * @throws java.lang.Exception
     * @see [类、类#方法、类#成员]
     */
    @Before
    public void setUp() throws Exception
    {
        SpringUtils springUtils = new SpringUtils(new String[]{"classpath:databaseContext.xml"});
        mapper = springUtils.getBean(RespondenceBeanMapper.class, "respondenceBeanMapper");
    }

    /**
     * Test method for {@link cn.edu.njfu.cs.eas.db.mapper.RespondenceBeanMapper#getRespondenceBeanByStudentIdANDTestPaperProblemIdBatch(java.util.Set, java.util.Set)}.
     */
    @Test
    public void testGetRespondenceBeanByStudentIdANDTestPaperProblemIdBatch()
    {
        Set<String> studentIds = new HashSet<String>();
        Set<String> testPaperProblemIds = new HashSet<String>();
        studentIds.add("535");
        testPaperProblemIds.add("27");
        studentIds.add("536");
        testPaperProblemIds.add("28");
        
        List<Set<String>> xxxargs = new ArrayList<Set<String>>();
        xxxargs.add(studentIds);
        xxxargs.add(testPaperProblemIds);
        List<RespondenceBean> ress = this.mapper.getRespondenceBeanByStudentIdANDTestPaperProblemIdBatch(xxxargs);
        System.out.println(ress.size());
    }

}
