8.3 SpringBoot集成ElasticSearch之删除文档

1.po开发
在项目目录“/src/main/java/com/example/es”下新建po目录，并在po目录下新建Employee实体类，具体代码如下。

@Data
public class Employee implements IdProvider {
    @JsonProperty("id")
    private String id;

    @JsonProperty("name")
    private String name;

    @JsonProperty("age")
    private Integer age;

    @JsonProperty("birthday")
    private String birthday;

    @JsonProperty("job")
    private String job;

    @JsonProperty("salary")
    private Float salary;

    @Override
    public String getId() {
        return id;
    }
}

2.mapper开发
在项目目录“/src/main/java/com/example/es”下新建mapper目录，并在mapper目录下新建EmployeeMapper接口，具体代码如下。

@EasyMapper(indices = "employee", clusterRouter = "sampleCluster")
public interface EmployeeMapper {
   
    @Delete
    Boolean deleteEmployeeBoolean(String id);

    
    @Delete
    void deleteEmployeeVoid(String id);

    
    @Delete
    RestStatus deleteEmployee(Employee employee);

    
    @Delete
    DeleteResponse deleteEmployeeDeleteResponse(String id);

    
    @Delete
    RestStatus deleteEmployee(String id);

    
    @Delete
    CompletableFuture deleteEmployeeBooleanFuture(String id);

    
    @Delete
    CompletableFuture deleteEmployeeVoidFuture(String id);
}

3.controller开发
在项目目录“/src/main/java/com/example/es”下新建controller目录，并在controller目录下新建EmployeeController类，以deleteEmployee接口为例演示开发步骤，具体代码如下。

@RestController
@RequestMapping("/employee")
public class EmployeeController {
    @Resource
    private EmployeeMapper employeeMapper;

    @ResponseBody
    @RequestMapping(value = "/deleteEmployee", method = RequestMethod.DELETE)
    public RestStatus deleteEmployee(@RequestBody Employee employee) {
        return employeeMapper.deleteEmployee(employee);
    }
}

4.测试
启动项目，然后在postman中请求“http://localhost:8080/employee/deleteEmployee”，返回请求执行结果。

{
    "id":"10001"
}

"OK"
