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

1.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>

2.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();
}
}

3.启动springboot,访问http://localhost:8081/swagger-ui.html
会发现页面显示报错：

后台报错：

2017-07-02 15:56:51.988 WARN 7176 --- [ qtp20577666-17] o.s.web.servlet.PageNotFound : No mapping found for HTTP request with URI [/swagger-ui.html] in DispatcherServlet with name 'dispatcherServlet'

想一下swagger-ui.html 是在springfox-swagger-ui.jar里的


如何才能让我们能访问到swagger-ui.html???
【百度到，MARK  http://www.jianshu.com/p/840320d431a1】

Spring Boot自动配置本身不会自动把/swagger-ui.html这个路径映射到对应的目录META-INF/resources/下面。我们加上这个映射即可。

/**

* @see XXXX <br>
*/
@Configuration
public class WebMVCConfig extends WebMvcConfigurerAdapter {
@Override
public void addResourceHandlers(ResourceHandlerRegistry registry) {
registry.addResourceHandler("swagger-ui.html")
.addResourceLocations("classpath:/META-INF/resources/");

          registry.addResourceHandler("/webjars/**")
                 .addResourceLocations("classpath:/META-INF/resources/webjars/");

}

}

再次启动springboot,访问http://localhost:8081/swagger-ui.html，OK：

4. 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” 

String convert to Long

由此看来，springboot集成Swagger2对接口有入侵，使用需谨慎。
