##### 数据修改 #####

我们做一个类似于 `update stu set sign='abc',age=33,money=88.6 where docId='1002'`的操作

@Test
    public void updateStuDoc() { 
    
        Map<String, Object> sourceMap = new HashMap<>();
        sourceMap.put("sign", "I am not super man");
        sourceMap.put("money", 88.6f);
        sourceMap.put("age", 33);
    
        IndexRequest indexRequest = new IndexRequest();
        indexRequest.source(sourceMap);
    
        UpdateQuery updateQuery = new UpdateQueryBuilder()
                                        .withClass(Stu.class)
                                        .withId("1003")
                                        .withIndexRequest(indexRequest)
                                        .build();
        esTemplate.update(updateQuery);
    }

我们查看一下结果，能看到数据已经修改成功了！

##### 数据查询 #####

类似于`select * from stu where docId='1002'`

@Test
    public void getStuDoc() { 
    
        GetQuery query = new GetQuery();
        query.setId("1002");
        Stu stu = esTemplate.queryForObject(query, Stu.class);
    
        System.out.println(stu);
    }

能看到打印结果

##### 数据删除 #####

类似于`delete from stu where docId='1002'`

@Test
    public void deleteStuDoc() { 
        
        esTemplate.delete(Stu.class, "1002");
    }
