SpringMVC项目接入Springfox

浏览数：429 / 时间：2015年06月08日

一、简介

Springfox的前身是swagger-springmvc,是一个开源的API doc框架，可以将我们的Controller的方法以文档的形式展现。

二、接入

1、pom依赖

1）必要

<!--springfox依赖-->
<dependency>
    <groupId>com.mangofactory</groupId>
    <artifactId>swagger-springmvc</artifactId>
    <version>1.0.2</version>
</dependency>
<!--jackson依赖-->
<dependency>
    <groupId>com.fasterxml.jackson.core</groupId>
    <artifactId>jackson-databind</artifactId>
    <version>2.4.2</version>
</dependency>
<!--静态页面依赖的webjar-->
<dependency>
    <groupId>org.webjars.bower</groupId>
    <artifactId>swagger-ui</artifactId>
    <version>2.1.8-M1</version>
</dependency>

2）如果项目依赖的Spring版本小于3.2.0.RELEASE则需要升级spring-web的依赖,以及guava的版本依赖

<dependency>
    <groupId>org.springframework</groupId>
    <artifactId>spring-web</artifactId>
    <version>3.2.0.RELEASE</version>
</dependency>
<dependency>
    <groupId>com.google.guava</groupId>
    <artifactId>guava</artifactId>
    <version>15.0</version>
</dependency>

2、Springfox配置文件

SpringfoxConfig类

        //.swaggerGroup(PROJECT_NAME);
    }

    private ApiInfo apiInfo() {
