在spring boot swagger中手动指定POST请求正文

import io.swagger.annotations.ApiImplicitParam;
import io.swagger.annotations.ApiImplicitParams;
import org.springframework.web.bind.annotation.PostMapping;
import org.springframework.web.bind.annotation.RequestBody;
import org.springframework.web.bind.annotation.RestController;

@RestController
public class MyController {

    @ApiImplicitParams({
            @ApiImplicitParam(name = "body", value = "请求正文", required = true, dataType = "String", paramType = "body")
    })
    @PostMapping("/api/myendpoint")
    public void myEndpoint(@RequestBody String body) {
        // 处理请求正文
    }
}
