简介

Swagger 是一个规范和完整的框架,用于生成、描述、调用和可视化 RESTful 风格的 Web 服务。总体目标是使客户端和文件系统作为服务器以同样的速度来更新。文件的方法,参数和模型紧密集成到服务器端的代码,允许API来始终保持同步。Swagger 让部署管理和使用功能强大的API从未如此简单。

这一次我将从零开始搭建一个工程来演示如何在Spring mvc中整合Swagger生成Restful接口文档。

新建工程

我们新建一个Maven工程,并添加Web Facet,工程结构如下图所示:

新建Maven工程

添加Maven依赖

<!--petstore是官方的一个demo,加入此依赖是为了稍后参考接口描述的编写-->

<dependency>

<groupId>io.springfox</groupId>

<artifactId>springfox-petstore</artifactId>

<version>${swagger.version}</version>

</dependency>

</dependencies>

添加配置

添加一个ApplicationInitializer类,用于配置DispatchServlet启动:

Image

在工程中的resources文件夹下新建一个spring的文件夹,并新建一个dispatcher-servlet.xml的spring mvc配置文件,添加如下内容:

Image

添加一个SwaggerConfig类,用于配置Swagger接口的说明:

Image

新建Controller

新建一个GroupController,并编写测试方法:

package yay.apidoc.controller;

import io.swagger.annotations.*;

import org.springframework.stereotype.Controller;

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

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

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

import yay.apidoc.model.UamGroup;

import java.util.LinkedList;

import java.util.List;

/**

* Created by yuananyun on 2015/11/23.

*/

@Controller

@RequestMapping(value = "/group", produces = {"application/json;charset=UTF-8"})

@Api(value = "/group", description = "群组的相关操作")

public class GroupController {

@RequestMapping(value = "addGroup", method = RequestMethod.PUT)

@ApiOperation(notes = "addGroup", httpMethod = "POST", value = "添加一个新的群组")

@ApiResponses(value = {@ApiResponse(code = 405, message = "invalid input")})

public UamGroup addGroup(@ApiParam(required = true, value = "group data") @RequestBody UamGroup group) {

return group;

}

@RequestMapping(value = "getAccessibleGroups", method = RequestMethod.GET)

@ApiOperation(notes = "getAccessibleGroups", httpMethod = "GET", value = "获取我可以访问的群组的列表")

public List<UamGroup> getAccessibleGroups() {

UamGroup group1 = new UamGroup();

group1.setGroupId("1");

group1.setName("testGroup1");

UamGroup group2 = new UamGroup();

group2.setGroupId("2");

group2.setName("testGroup2");

List<UamGroup> groupList = new LinkedList<UamGroup>();

groupList.add(group1);

groupList.add(group2);

return groupList;

}

}

其中UamGroup的定义如下:

package yay.apidoc.model;

import io.swagger.annotations.ApiModel;

import io.swagger.annotations.ApiModelProperty;

/**

* 群组

*/

@ApiModel

public class UamGroup {

/**

* 编号

*/

@ApiModelProperty(value = "群组的Id", required = true)

private String groupId;

/**

* 名称

*/

@ApiModelProperty(value = "群组的名称", required = true)

private String name;

/**

* 群组图标

*/

@ApiModelProperty(value = "群组的头像", required = false)

private String icon;

public String getGroupId() {

return groupId;

}

public void setGroupId(String groupId) {

this.groupId = groupId;

}

public String getName() {

return name;

}

public void setName(String name) {

this.name = name;

}

public String getIcon() {

return icon;

}

public void setIcon(String icon) {

this.icon = icon;

}

}

好,目前为止我们的代码已经编写完成,整个工程的目录结构如下:

Image

为了让Swagger能够扫描Spring mvc中定义的Controller,我们需要在mvc的配置文件里面定义扫描的路径和相关的bean:

Image

添加Swagger ui

在GitHub上下载SwaggerUI项目,将dist下所有内容拷贝到本地项目apidoc/web下面,结果目录如下图所示:

Image

打开目录下的index.html文件,找到代码片段url = "http://petstore.swagger.io/v2/swagger.json";修改为“/apidoc/v2/api-docs”。

为了让网页显示中文,我们可以取消注释以下脚本:

Image

为了能够访问index.html页面,我们在dispatcher-servlet.xml中添加如下配置:

<!-- Enables swgger ui-->

<mvc:resources mapping="*.html" location="/"/>

<mvc:resources mapping="/**" location="/"/>

好,现在我们启动tomcat来看看效果:

解决中文乱码

可以看到,我们写在方法上说明居然成了乱码,为了解决这个问题,我们新建一个转换类:

package yay.apidoc.converter;

import com.fasterxml.jackson.annotation.JsonInclude;

import com.fasterxml.jackson.databind.*;

import org.springframework.http.HttpInputMessage;

import org.springframework.http.converter.HttpMessageNotReadableException;

import org.springframework.http.converter.json.MappingJackson2HttpMessageConverter;

import java.io.IOException;

import java.text.SimpleDateFormat;

/**

* Created by yuananyun on 2015/11/23.

*/

public class MappingJacksonHttpMessageConverterEx extends MappingJackson2HttpMessageConverter {

private ObjectMapper objectMapper = new ObjectMapper();

public MappingJacksonHttpMessageConverterEx() {

super();

DeserializationConfig deserializationConfig = objectMapper.getDeserializationConfig()

.without(DeserializationFeature.FAIL_ON_UNKNOWN_PROPERTIES);

objectMapper.setConfig(deserializationConfig);

// Configure serialization

SerializationConfig serializationConfig = objectMapper.getSerializationConfig()

.without(SerializationFeature.FAIL_ON_EMPTY_BEANS);

//serializationConfig.withDateFormat(new SimpleDateFormat("yyyy-MM-dd HH:mm:ss"));

objectMapper.setConfig(serializationConfig);

objectMapper.setDateFormat(new SimpleDateFormat("yyyy-MM-dd HH:mm:ss"));

objectMapper.setSerializationInclusion(JsonInclude.Include.NON_NULL);

// objectMapper.configure(SerializationFeature.WRITE_DATES_AS_TIMESTAMPS, true);

objectMapper.configure(SerializationFeature.ORDER_MAP_ENTRIES_BY_KEYS,true);

setObjectMapper(objectMapper);

}

@Override

protected Object readInternal(Class<?> clazz, HttpInputMessage inputMessage)

throws IOException, HttpMessageNotReadableException {

JavaType javaType = getJavaType(null, clazz);

return this.objectMapper.readValue(inputMessage.getBody(), javaType);

}

}

然后修改dispatcher-servlet.xml中的mvc:annotation-driven配置节:

<!-- Standard xml based mvc config-->

<mvc:annotation-driven>

<mvc:message-converters>

<bean class="org.springframework.http.converter.StringHttpMessageConverter">

<property name="supportedMediaTypes">

<list>

<value>text/html;charset=UTF-8</value>

</list>

</property>

</bean>

<bean class="yay.apidoc.converter.MappingJacksonHttpMessageConverterEx"/>

<bean class="org.springframework.http.converter.ResourceHttpMessageConverter"/>

</mvc:message-converters>

</mvc:annotation-driven>

我们再来看看效果:
