3.核心代码

---

@RestController
@RequiredArgsConstructor(onConstructor = @__(@Autowired))
public class TestUseEeController {
    private final DocumentMapper documentMapper;

    @GetMapping("/index")
    public Boolean index() {
        // 初始化-> 创建索引,相当于MySQL建表 | 此接口须首先调用,只调用一次即可
        LambdaEsIndexWrapper<Document> indexWrapper = new LambdaEsIndexWrapper<>();
        indexWrapper.indexName(Document.class.getSimpleName().toLowerCase());
        indexWrapper.mapping(Document::getTitle, FieldType.KEYWORD)
                .mapping(Document::getContent, FieldType.TEXT);
        documentMapper.createIndex(indexWrapper);
        return Boolean.TRUE;
    }

    @GetMapping("/insert")
    public Integer insert() {
        // 初始化-> 新增数据
        Document document = new Document();
        document.setTitle("老汉");
        document.setContent("推*技术过硬");
        return documentMapper.insert(document);
    }

    @GetMapping("/search")
    public List<Document> search() {
        // 查询出所有标题为老汉的文档列表
        LambdaEsQueryWrapper<Document> wrapper = new LambdaEsQueryWrapper<>();
        wrapper.eq(Document::getTitle, "老汉");
        return documentMapper.selectList(wrapper);
    }
}

4.启动及使用

---

a.添加配置信息

easy-es:
  enable: true # 默认为true,若为false时,则认为不启用本框架
  address : 127.0.0.0:9200  #填你的es连接地址
  # username: 有设置才填写,非必须
  # password: 有设置才填写,非必须

b.启动项目

使用你的IDE启动项目

c.使用

依次在浏览器访问
http://localhost:8080/index (仅访问一次即可,完成索引创建,相当于MySQL建表,有了表才能进行后续CRUD)

http://localhost:8080/insert (插入数据)

http://localhost:8080/search (查询)

效果图:
