1.检查swagger的jar包版本号

如果springfox 2.5及以上,

需要使用一下方式放行swagger

/**
     * 配置无需登陆就可以访问的路径
     *
     * @param web
     * @throws Exception
     */
    @Override
    public void configure(WebSecurity web) throws Exception {
        //allow Swagger URL to be accessed without authentication
        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", "/doc.html");
    }

2.5一下的, 使用

@Configuration
public class WebSecurityConfiguration extends WebSecurityConfigurerAdapter {

    @Override
    public void configure(WebSecurity web) throws Exception {
        web.ignoring().antMatchers("/v2/api-docs", "/configuration/ui", "/swagger-resources", "/configuration/security", "/swagger-ui.html", "/webjars/**");
    }

}
