SpringBoot集成Swagger2实现Restful(类型转换错误解决办法)

pom.xml增加依赖包

<dependency>
<groupId>io.springfox</groupId>
<artifactId>springfox-swagger2</artifactId>
<version>2.2.2</version>
</dependency>
<dependency>
<groupId>io.springfox</groupId>
<artifactId>springfox-swagger-ui</artifactId>
<version>2.2.2</version>
</dependency>

编写swapper2配置类

package com.zyank;

import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;

import springfox.documentation.builders.ApiInfoBuilder;
import springfox.documentation.builders.PathSelectors;
import springfox.documentation.builders.RequestHandlerSelectors;
import springfox.documentation.service.ApiInfo;
import springfox.documentation.spi.DocumentationType;
import springfox.documentation.spring.web.plugins.Docket;
import springfox.documentation.swagger2.annotations.EnableSwagger2;

@Configuration
@EnableSwagger2
public class Swagger2 {

@Bean
public Docket createRestApi() {

return new Docket(DocumentationType.SWAGGER_2)
.apiInfo(apiInfo())
.select()
.apis(RequestHandlerSelectors.basePackage("com.zyank.web"))
.paths(PathSelectors.any())
.build();
}

private ApiInfo apiInfo(){

return new ApiInfoBuilder()
.title("Spring Boot中试用Swagger2构建的RESTful APIs")
.description("更多Spring Boot相关文章请关注：http://blog.didispace.com/")
.termsOfServiceUrl("http://blog.didispace.com/")
.contact("leo")
.version("1.0")
.build();

}

}

Controller内使用

package com.zyank.web;

import java.util.ArrayList;
import java.util.Collections;
import java.util.HashMap;
import java.util.List;
import java.util.Map;

import org.springframework.web.bind.annotation.PathVariable;
import org.springframework.web.bind.annotation.RequestBody;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RequestMethod;
import org.springframework.web.bind.annotation.RestController;

import com.zyank.domain.User;

import io.swagger.annotations.ApiImplicitParam;
import io.swagger.annotations.ApiImplicitParams;
import io.swagger.annotations.ApiOperation;

@RestController
@RequestMapping(value="/users")
public class UserContrller {

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

@ApiOperation(value="获取用户列表",notes="")
@RequestMapping(value={""},method=RequestMethod.GET)
public List<User> getUserList(){

List<User> r=new ArrayList<User>(users.values());

return r;
}

@ApiOperation(value="创建用户", notes="根据User对象创建用户")
@ApiImplicitParam(name = "user", value = "用户详细实体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="获取用户详细信息", notes="根据url的id来获取用户详细信息")
@ApiImplicitParam(name = "id", value = "用户ID", required = true, paramType="path", dataType = "Long")
@RequestMapping(value="/{id}", method=RequestMethod.GET)
public User getUser(@PathVariable Long id) {
return users.get(id);
}
@ApiOperation(value="更新用户详细信息", notes="根据url的id来指定更新对象，并根据传过来的user信息来更新用户详细信息")
@ApiImplicitParams({
@ApiImplicitParam(name = "id", value = "用户ID", required = true, paramType="path", dataType = "Long"),
@ApiImplicitParam(name = "user", value = "用户详细实体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="删除用户", notes="根据url的id来指定删除对象")
@ApiImplicitParam(name = "id", value = "用户ID", required = true, dataType = "Long")
@RequestMapping(value="/{id}", method=RequestMethod.DELETE)
public String deleteUser(@PathVariable Long id) {
users.remove(id);
return "success";
}

}

如果上诉代码没有写paramType = “path” 会提示类型转换String convert to Long错误。
