controller

import com.example.thymeleafdemo.domain.User;
import io.swagger.annotations.ApiImplicitParam;
import io.swagger.annotations.ApiImplicitParams;
import io.swagger.annotations.ApiOperation;
import org.springframework.web.bind.annotation.*;

import java.util.*;

@RestController
@RequestMapping("/users")
public class UserController {

    static Map<Long,User> users= Collections.synchronizedMap(new HashMap<Long,User>());


    @ApiOperation(value="獲取用戶列表", notes="")
    @RequestMapping(value={""}, method= RequestMethod.GET)
    public List<User> getUserList() {
        List<User> r = new ArrayList<User>(users.values());
        return r;
    }
    @ApiOperation(value="創建用戶", notes="根據User對象創建用戶")
    @ApiImplicitParam(name = "user", value = "用戶詳細實體user", required = true, dataType = "User")
    @RequestMapping(value="", method=RequestMethod.POST)
    public String postUser(@RequestBody User user) {
        users.put(user.getId(), user);
        return "success";
    }
    @ApiOperation(value="獲取用戶詳細信息", notes="根據url的id來獲取用戶詳細信息")
    @ApiImplicitParam(name = "id", value = "用戶ID",paramType = "path",required = true, dataType = "Long")
    @RequestMapping(value="/{id}", method=RequestMethod.GET)
    public User getUser(@PathVariable Long id) {
        return users.get(id);
    }
    @ApiOperation(value="更新用戶詳細信息", notes="根據url的id來指定更新對象，並根據傳過來的user信息來更新用戶詳細信息")
    @ApiImplicitParams({
            @ApiImplicitParam(name = "id", value = "用戶ID",paramType = "path", required = true, dataType = "Long"),
            @ApiImplicitParam(name = "user", value = "用戶詳細實體user", required = true, dataType = "User")
    })
    @RequestMapping(value="/{id}", method=RequestMethod.PUT)
    public String putUser(@PathVariable Long id, @RequestBody User user) {
        User u = users.get(id);
        u.setName(user.getName());
        u.setAge(user.getAge());
        users.put(id, u);
        return "success";
    }
    @ApiOperation(value="刪除用戶", notes="根據url的id來指定刪除對象")
    @ApiImplicitParam(name = "id", value = "用戶ID",paramType = "path", required = true, dataType = "Long")
    @RequestMapping(value="/{id}", method=RequestMethod.DELETE)
    public String deleteUser(@PathVariable Long id) {
        users.remove(id);
        return "success";
    }
}

如果 @ApiImplicitParam(name = "id", value = "用戶ID",paramType = "path", required = true, dataType = "Long") 沒有paramType = "path"會提示類型轉換String convert to Long錯誤。

SpringBoot集成Swagger2實現Restful(類型轉換錯誤解決辦法)
