需要在service使用多主键相关操作包括saveOrUpdateByMultiId和批量操作updateBatchByMultiId和saveOrUpdateBatchByMultiId,可以直接继承IMppService接口。
service层继承IMppService接口和MppServiceImpl
public interface Test07Service extends IMppService<Test07Entity> { } public class Test07ServiceImpl extends MppServiceImpl<Test07Mapper, Test07Entity> implements Test07Service { }
在service层根据复合主键进行批量操作和saveOrUpdate操作
@Test public void testSaveOrUpdateByMultiIdService(){ //id Test07Entity idEntity=new Test07Entity(); idEntity.setK1(6); idEntity.setK2("666"); //del test07Service.deleteByMultiId(idEntity); //add test07Service.saveOrUpdateByMultiId(idEntity); //update idEntity.setCol1("ccccc"); test07Service.saveOrUpdateByMultiId(idEntity); } @Test public void testSaveOrUpdateBatchByMultiIdService(){ //ids List<Test07Entity> entityList=new ArrayList<Test07Entity>(); for(int i=10;i<30;i++){ Test07Entity idEntity=new Test07Entity(); idEntity.setK1(i); idEntity.setK2(String.valueOf(i*10)); entityList.add(idEntity); } //del for(Test07Entity idEntity:entityList) { test07Service.deleteByMultiId(idEntity); } //add batch test07Service.saveOrUpdateBatchByMultiId(entityList); //del for(Test07Entity idEntity:entityList) { idEntity.setCol1(new Date().toString()); } //update batch test07Service.saveOrUpdateBatchByMultiId(entityList); } @Test public void testUpdateBatchByMultiIdService(){ //ids List<Test07Entity> entityList=new ArrayList<Test07Entity>(); for(int i=50;i<80;i++){ Test07Entity idEntity=new Test07Entity(); idEntity.setK1(i); idEntity.setK2(String.valueOf(i*10)); entityList.add(idEntity); } //del for(Test07Entity idEntity:entityList) { test07Service.deleteByMultiId(idEntity); } //add batch test07Service.saveOrUpdateBatchByMultiId(entityList); //del for(Test07Entity idEntity:entityList) { idEntity.setCol1(new Date().toString()); } //update batch test07Service.updateBatchByMultiId(entityList); }
