## 3.核心代码

|
|
|
|
```java
|
|
@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
|
|
```yaml
|
|
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<br />
|
|
|
|
|
|
|
|
### c.使用
|
|
依次在浏览器访问<br />[http://localhost:8080/index](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](http://localhost:8080/insert) (插入数据)
|
|
|
|
[http://localhost:8080/search](http://localhost:8080/search) (查询)
|
|
|
|
