SpringBoot + Elasticsearch：数据修改、查询与删除_springboot elasticsearch数据清空,使查询不报错

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);
}
