JPA 동적 쿼리문(자세한 코드 설명)

JPA动态查询语句（代码详解）

我们现在在做一个OA系统，将新增的那些数据都写到数据库的时候是采用jpa规范的，（不太理解jpa的相关知识点，今天看下相关知识，然后再补充jpa的知识点），现在记录jpa中的动态查询语句，其实这些语句都是可以用sql语句写的，但是sql语句写得查询，删除，插入数据等操作不安全，所以采用jpa的语句。我们的项目是分为三层结构，第一层是实体层，在该层中专门定义某一实体的相关字段，它的set()，get()方法。第二层是服务层，将service和dao都放在一个组件中,在dao层中定义和数据库相关的操作方法，在service层中定义相关的业务逻辑层要调用的方法。第三层是restful层，在这层定义的是和前端交互的组件。

首先讲讲第一层：实体层

定义一个实体

动态查询语句的相关知识

1：查询User表中的字段adminlever的小于给定值的数据

第一种写法：（安全，推荐使用这种）

/**
	* 查询某一级别以上的用户
	*/  
   @Override  
   public List<User> getOnLeverUper(int lever) {  
	 CriteriaBuilder cb =entityManager.getCriteriaBuilder();  
	 CriteriaQuery<User> criterQuery=cb.createQuery(User.class);  
	 Root<User> entity=criterQuery.from(User.class);  
	 Path<Integer> adminLever=entity.<Integer> get("adminlever") ;  
	 criterQuery.where(cb.lessThan(adminLever, lever));  
	 TypedQuery<User> typedQuery=entityManager.createQuery(criterQuery);  
	 return typedQuery.getResultList();  
	
   }

第二种写法：(不太安全，)

/**
	* 查询某一级别以上的用户
	*/  
   @Override  
   public List<User> getOnLeverUper(int lever) {  
	   List<User> users=entityManager.createQuery("from User u where u.adminlever<:adminlever")  
			   .setParameter("adminlever",lever).getResultList();

第二种删除数据（有时候会由于某实体和另一实体设置了一对一或者多对一，或者多对多的关系而导致不能正常删除数据），解决方法：

/**
	 * 删除登记信息
	 *  
	 * @param id
	 *			登记编号
	 */  
	@Override  
	public void handleDelete(long id) throws Exception {  
		ReceiptEntity entity = entityManager.find(ReceiptEntity.class, id);  
		entityManager.remove(entity);  
		//下面的的方法删除应为存在外键关联会删除失败  
	   /*entityManager.createQuery("delete from  ReceiptEntity e where e.id=:id").
		setParameter("id", id).executeUpdate();*/

在添加一个正常的测试新增的方法：

@Test
public void testAdd(){
  LOG.info("开始测试增加");
  PostMethod post = new PostMethod(TEST_URL);
  post.addRequestHeader("Accept", "application/json");
  post.getParams().setParameter(HttpMethodParams.HTTP_CONTENT_CHARSET,
	"UTF-8");
  try {
   JSONObject jo = new JSONObject();
  
   jo.put("day", "2015-4-10");
   jo.put("type", "0");
   jo.put("content", "gfdz参加了2014年广东省某某某某活动");
   jo.put("mainLeaderIds", "2,3");
   jo.put("relevantLeaderIds", "5,6");
   // date
   jo.put("goverEvent", true);
   jo.put("ownEvent", false);
   jo.put("ownerId", "2");
   LOG.debug("设置请求参数：" + jo.toString());
   RequestEntity entity = new StringRequestEntity(
	 jo.toString(), "application/json", "UTF-8");
   post.setRequestEntity(entity);
   HttpClient httpclient = new HttpClient();
   String res = "";
   LOG.info("发送post请求");
   int result = httpclient.executeMethod(post);
   LOG.info(" 响应状态：" + result);
   res = this.getStringFromInputStream(post.getResponseBodyAsStream());
   LOG.info("响应结果：：" + res);
   Assert.assertTrue(res.contains("增加值班表"));
  } catch (Exception e) {
   LOG.error("测试错误", e);
   Assert.fail("连接出错");
  } finally {
   post.releaseConnection();
