SpringBoot配置swagger2

1.引入依赖（Ps：2.9.2直接配置就可成功，但3.0的版本好像有些其他地方需要配置）

	<dependency>
            <groupId>io.springfox</groupId>
            <artifactId>springfox-swagger-ui</artifactId>
            <version>2.9.2</version>
        </dependency>
        <dependency>
            <groupId>io.springfox</groupId>
            <artifactId>springfox-swagger2</artifactId>
            <version>2.9.2</version>
        </dependency>

2.配置类注解

@EnableSwagger2

3.可选，若配置了springsecurity

	 @Override
    public void configure(WebSecurity web) throws Exception {
        web.ignoring().antMatchers("/v2/api-docs",//swagger api json
                "/swagger-resources/configuration/ui",//用来获取支持的动作
                "/swagger-resources",//用来获取api-docs的URI
                "/swagger-resources/configuration/security",//安全选项
                "/swagger-ui.html");//        super.configure(web);
    }
