一步步完成Maven+SpringMVC+SpringFox+Swagger整合示例

2022-09-29 17:07:57

本文给出一个整合Maven+SpringMVC+SpringFOX+Swagger的示例，并且一步步给出完成步骤。

本人在做实例时发现 http://blog.csdn.net/zth1002/article/details/46927187 中，Spring必须是4.0以上版本。

目标

在做项目的时候，有时候需要提供其它平台（如业务平台）相关的HTTP接口，业务平台则通过开放的HTTP接口获取相关的内容，并完成自身业务~

提供对外开放HTTP API接口，比较常用的是采用Spring MVC来完成。

本文的目标是先搭建一个简单的Spring MVC应用，然后为Spring MVC整合SpringFox-Swagger以及SpringFox-Swagger-UI，最终，达到Spring MVC对外开放接口API文档化。

如下图所示：

一步步完成Maven+SpringMVC+SpringFox+Swagger整合示例

搭建SpringMVC工程

新建Maven工程

Eclipse中，File --> New --> Maven Project，

但是，

默认是使用J2SE-1.5，配置一下Build Path，使用本地机器上安装的JDK

（本文中使用的是JDK 1.7），工程默认字体是GBK，将其改成UTF-8

完成后，Maven工程的结构如下图所示：

引入Spring依赖包

在本示例中，因为简单，所以只要引入如下几个jar包就好了~

	<dependencies>

		<!--引入Spring依赖包 -->

		<dependency>

			<groupId>org.springframework</groupId>

			<artifactId>spring-core</artifactId>

			<version>${spring.framework.version}</version>

		</dependency>

		<dependency>

			<groupId>org.springframework</groupId>

			<artifactId>spring-context</artifactId>

		</dependency>

		<dependency>

			<groupId>org.springframework</groupId>

			<artifactId>spring-webmvc</artifactId>

			<version>${spring.framework.version}</version>

		</dependency>

	</dependencies>

完整的pom.xml文件内容如下：

			<version>${spring.framework.version}</version>

		</dependency>

	</dependencies><build><finalName>springfox-swagger-demo</finalName></build></project>

编写spring-mvc.xml文件

<?xml version="1.0" encoding="UTF-8"?>

<beans xmlns="http://www.springframework.org/schema/beans"

	xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:context="http://www.springframework.org/schema/context"

	xmlns:mvc="http://www.springframework.org/schema/mvc" xmlns:p="http://www.springframework.org/schema/p"

		http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context-4.0.xsd

		http://www.springframework.org/schema/mvc http://www.springframework.org/schema/mvc/spring-mvc-4.0.xsd">

	<!-- 默认的注解映射的支持 ,它会自动注册DefaultAnnotationHandlerMapping 与AnnotationMethodHandlerAdapter -->

	<mvc:annotation-driven />

	<!-- enable autowire 向容器自动注册 -->

	<context:annotation-config />

	<!-- 设置使用注解的类所在的jar包 -->

	<context:component-scan base-package="com.xxx.tutorial" />

	<bean

		class="org.springframework.web.servlet.mvc.annotation.AnnotationMethodHandlerAdapter" />

</beans>

配置web.xml

<?xml version="1.0" encoding="UTF-8"?>

<web-app xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"

	xmlns="http://java.sun.com/xml/ns/javaee"

	</filter>

	<filter-mapping>

		<filter-name>encodingFilter</filter-name>

		<url-pattern>/*</url-pattern>

	</filter-mapping>

</web-app>

编写Controller并测试

配置好spring-mvc.xml以及web.xml文件之后，咱们继续往下走~

因为，本文Spring MVC示例的作用主要用来暴露对外HTTP API接口，先写一个简单的ProductController，其包含一个按照id查询的方法。

Product.java和ProductController.java的内容如下：

Product.java

package com.xxx.tutorial.model;

import java.io.Serializable;

/**

 *

 * @author wangmengjun

 *

 */

public class Product implements Serializable {

	private static final long serialVersionUID = 1L;

	/**ID*/

	private Long id;

	/**产品名称*/

	private String name;

	/**产品型号*/

	private String productClass;

	/**产品ID*/

	private String productId;

	/**

	 * @return the id

	 */

	public Long getId() {

		return id;

	}

	/**

	 * @param id

	 *            the id to set

	 */

	public void setId(Long id) {

		this.id = id;

	}

	/**

	 * @return the name

	 */

	public String getName() {

		return name;

	}

	/**

	 * @param name

	 *            the name to set

	 */

	public void setName(String name) {

		this.name = name;

	}

	/**

	 * @return the productClass

	 */

	public String getProductClass() {

		return productClass;

	}

	/**

	 * @param productClass

	 *            the productClass to set

	 */

	public void setProductClass(String productClass) {

		this.productClass = productClass;

	}

	/**

	 * @return the productId

	 */

	public String getProductId() {

		return productId;

	}

	/**

	 * @param productId

	 *            the productId to set

	 */

	public void setProductId(String productId) {

		this.productId = productId;

	}

	/*

	 * (non-Javadoc)

	 *

	 * @see java.lang.Object#toString()

	 */

	@Override

	public String toString() {

		return "Product [id=" + id + ", name=" + name + ", productClass=" + productClass + ", productId=" + productId

				+ "]";

	}

}

ProductController.java

package com.xxx.tutorial.controller;

import org.springframework.http.ResponseEntity;

import org.springframework.web.bind.annotation.PathVariable;

import org.springframework.web.bind.annotation.RequestMapping;

import org.springframework.web.bind.annotation.RequestMethod;

import org.springframework.web.bind.annotation.RestController;

import com.xxx.tutorial.model.Product;

@RestController

@RequestMapping(value = { "/api/product/"})

public class ProductController {

	@RequestMapping(value = "/{id}", method = RequestMethod.GET)

	public ResponseEntity<Product> get(@PathVariable Long id) {

		Product product = new Product();

		product.setName("七级滤芯净水器");

		product.setId(1L);

		product.setProductClass("seven_filters");

		product.setProductId("T12345");

		return ResponseEntity.ok(product);

	}

}

注：

鉴于是一个demo示例，所以没有写ProductService以及相关DAO, 直接在方法中返回固定的Product信息~

验证Spring MVC是否ok

完成Controller的代码，运行Spring MVC项目，然后，看一下Spring MVC是否运行ok，访问URL地址

http://localhost:8888/springfox-swagger-demo/api/product/1

出现错误

解决方法，添加jackson-databind依赖包即可~

		<dependency>

			<groupId>com.fasterxml.jackson.core</groupId>

			<artifactId>jackson-databind</artifactId>

			<version>2.6.6</version>

		</dependency>

重新启动，运行一下，成功返回信息~

为了看的更加清楚，可以使用postman来完成~，如~

一步步完成Maven+SpringMVC+SpringFox+Swagger整合示例

至此，一个简单的基于SpringMVC的Web项目已经创建，并能对外提供API接口~

一步步完成Maven+SpringMVC+SpringFox+Swagger整合示例

接下来，我们要整合SpringFox和SwaggerUI到该SpringMVC项目中去，使其对外接口文档化

整合SpringFox-Swagger

SpringFox【SpringFox链接】已经可以代替Swagger-SpringMVC, 目前SpringFox同时支持Swagger 1.2 和 2.0.

在SpringMVC项目中整合SpringFox-Swagger只要如下几步即可~

添加SpringFox-Swagger依赖
添加SwaggerConfig

添加依赖

		<dependency>

			<groupId>io.springfox</groupId>

			<artifactId>springfox-swagger2</artifactId>

			<version>2.7.0</version>

		</dependency>

添加SwaggerConfig

package com.xxx.tutorial.config;

import org.springframework.context.annotation.Bean;

import org.springframework.context.annotation.Configuration;

import springfox.documentation.builders.ApiInfoBuilder;

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 SwaggerConfig {

	@Bean

	public Docket api() {

		return new Docket(DocumentationType.SWAGGER_2)

				.select()

				.apis(RequestHandlerSelectors.any())

				.build()

				.apiInfo(apiInfo());

	}

	private ApiInfo apiInfo() {

		return new ApiInfoBuilder()

				.title("对外开放接口API 文档")

				.description("HTTP对外开放接口")

				.version("1.0.0")

				.termsOfServiceUrl("http://xxx.xxx.com")

				.license("LICENSE")

				.licenseUrl("http://xxx.xxx.com")

				.build();

	}

}

整合SpringFox-Swagger-UI

在SpringMVC项目中整合SpringFox-Swagger-UI也只要如下两个步骤即可~

添加SpringFox-Swagger-UI依赖
添加配置

添加依赖

		<dependency>

			<groupId>io.springfox</groupId>

			<artifactId>springfox-swagger-ui</artifactId>

			<version>2.7.0</version>

		</dependency>

添加配置

在添加配置之前，一起来看一下swagger-ui中使用的静态资源文件（如swagger-ui.html ）放在那里~

spingfox-swagger-ui-2.7.0.jar中的/META-INF/resources/下~ 如下图所示：

一步步完成Maven+SpringMVC+SpringFox+Swagger整合示例

为了访问swagger-ui.html，我们配置对这些静态资源的访问~ 如：

package com.xxx.tutorial.config;

import org.springframework.context.annotation.Configuration;

import org.springframework.web.servlet.config.annotation.EnableWebMvc;

import org.springframework.web.servlet.config.annotation.ResourceHandlerRegistry;

import org.springframework.web.servlet.config.annotation.WebMvcConfigurerAdapter;

@Configuration

@EnableWebMvc

public class WebAppConfig 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/");

    }

}

该配置代码的效果和如下代码等价~

	<mvc:resources mapping="swagger-ui.html" location="classpath:/META-INF/resources/" />

	<mvc:resources mapping="/webjars/**"

		location="classpath:/META-INF/resources/webjars/" />

在本文中，可以将其配置在spring-mvc.xml中，

<?xml version="1.0" encoding="UTF-8"?>

<beans xmlns="http://www.springframework.org/schema/beans"

	xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:context="http://www.springframework.org/schema/context"

	xmlns:mvc="http://www.springframework.org/schema/mvc" xmlns:p="http://www.springframework.org/schema/p"

	xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans-4.0.xsd

		http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context-4.0.xsd

		http://www.springframework.org/schema/mvc http://www.springframework.org/schema/mvc/spring-mvc-4.0.xsd">

	<!-- 默认的注解映射的支持 ,它会自动注册DefaultAnnotationHandlerMapping 与AnnotationMethodHandlerAdapter -->

	<mvc:annotation-driven />

	<!-- enable autowire 向容器自动注册 -->

	<context:annotation-config />

	<!-- 设置使用注解的类所在的jar包 -->

	<context:component-scan base-package="com.xxx.tutorial" />

	<bean

		class="org.springframework.web.servlet.mvc.annotation.AnnotationMethodHandlerAdapter" />

	<mvc:resources mapping="swagger-ui.html" location="classpath:/META-INF/resources/" />

	<mvc:resources mapping="/webjars/**"

		location="classpath:/META-INF/resources/webjars/" />

</beans>

API接口说明代码添加并测试

经过上述几个步骤之后，之前写的ProductController的接口，就可以实现文档化了，如本文通过如下的访问地址访问：

http://localhost:8888/springfox-swagger-demo/swagger-ui.html

一步步完成Maven+SpringMVC+SpringFox+Swagger整合示例

这个接口API雏形出来了，但是还缺少点东西，比如：接口方法的描述等都没有~

修改一下，ProductController.java内容，如：

package com.xxx.tutorial.controller;

import org.springframework.http.ResponseEntity;

import org.springframework.web.bind.annotation.PathVariable;

import org.springframework.web.bind.annotation.RequestMapping;

import org.springframework.web.bind.annotation.RequestMethod;

import org.springframework.web.bind.annotation.RestController;

import com.xxx.tutorial.model.Product;

import io.swagger.annotations.Api;

import io.swagger.annotations.ApiOperation;

@RestController

@RequestMapping(value = { "/api/product/" })

@Api(value = "/product", tags = "Product接口")

public class ProductController {

	@RequestMapping(value = "/{id}", method = RequestMethod.GET)

	@ApiOperation(value = "根据id获取产品信息", notes = "根据id获取产品信息", httpMethod = "GET", response = Product.class)

	public ResponseEntity<Product> get(@PathVariable Long id) {

		Product product = new Product();

		product.setName("七级滤芯净水器");

		product.setId(1L);

		product.setProductClass("seven_filters");

		product.setProductId("T12345");

		return ResponseEntity.ok(product);

	}

}

重新访问，接口已经出现多个我们指定的描述信息~

一步步完成Maven+SpringMVC+SpringFox+Swagger整合示例

在参数id栏中输入1，然后点击“try it out”按钮~ 可以查看接口调用结果~

一步步完成Maven+SpringMVC+SpringFox+Swagger整合示例

至此一个简单的示例就完成了~

稍微增加几个接口

修改ProductController

package com.xxx.tutorial.controller;

import java.util.Arrays;

import java.util.List;

import org.springframework.http.ResponseEntity;

import org.springframework.web.bind.annotation.PathVariable;

import org.springframework.web.bind.annotation.RequestMapping;

import org.springframework.web.bind.annotation.RequestMethod;

import org.springframework.web.bind.annotation.RestController;

import com.xxx.tutorial.model.Product;

import io.swagger.annotations.Api;

import io.swagger.annotations.ApiOperation;

import io.swagger.annotations.ApiResponse;

import io.swagger.annotations.ApiResponses;

@RestController

@RequestMapping(value = { "/api/product/" })

@Api(value = "/product", tags = "Product接口")

public class ProductController {

	@RequestMapping(value = "/{id}", method = RequestMethod.GET)

	@ApiOperation(value = "根据id获取产品信息", notes = "根据id获取产品信息", httpMethod = "GET", response = Product.class)

	public ResponseEntity<Product> get(@PathVariable Long id) {

		Product product = new Product();

		product.setName("七级滤芯净水器");

		product.setId(1L);

		product.setProductClass("seven_filters");

		product.setProductId("T12345");

		return ResponseEntity.ok(product);

	}

	@RequestMapping(method = RequestMethod.POST)

	@ApiOperation(value = "添加一个新的产品")

	@ApiResponses(value = { @ApiResponse(code = 405, message = "参数错误") })

	public ResponseEntity<String> add(Product product) {

		return ResponseEntity.ok("SUCCESS");

	}

	@RequestMapping(method = RequestMethod.PUT)

	@ApiOperation(value = "更新一个产品")

	@ApiResponses(value = { @ApiResponse(code = 400, message = "参数错误") })

	public ResponseEntity<String> update(Product product) {

		return ResponseEntity.ok("SUCCESS");

	}

	@RequestMapping(method = RequestMethod.GET)

	@ApiOperation(value = "获取所有产品信息", notes = "获取所有产品信息", httpMethod = "GET", response = Product.class, responseContainer = "List")

	public ResponseEntity<List<Product>> getAllProducts() {

		Product product = new Product();

		product.setName("七级滤芯净水器");

		product.setId(1L);

		product.setProductClass("seven_filters");

		product.setProductId("T12345");

		return ResponseEntity.ok(Arrays.asList(product, product));

	}

}

swagger-ui展示

一步步完成Maven+SpringMVC+SpringFox+Swagger整合示例

由上图可以看出，不同的method（GET / PUT / POST等）都会以不同的颜色展示出来~

Swagger-ui的添加，可以帮助他人查看接口信息，并在页面上进行输入参数来调用接口~
