公司遇到的问题处理

一、搭建springboot项目的步骤及配置

1、创建maven项目

2、修改端口配置文件

3、创建引导类（@SpringBootAplication）

SpringApplication.run(Demo.class, args);

二、SpringBoot项目，页面调用宁一个ip的接口，跨域解决

1、写一个类

public class CorsFilter implements Filter {

    @Override

    public void init(FilterConfig filterConfig) throws ServletException {

 

    }

 

    @Override

    public void doFilter(ServletRequest servletRequest, ServletResponse servletResponse, FilterChain filterChain) throws IOException, ServletException {

        HttpServletResponse response = (HttpServletResponse) servletResponse;

        HttpServletRequest request = (HttpServletRequest)servletRequest;

 

        String origin = request.getHeader("Origin");

        response.setHeader("Access-Control-Allow-Origin", origin);

        response.setHeader("Access-Control-Allow-Methods", "POST, GET, OPTIONS, DELETE");

        response.setHeader("Access-Control-Max-Age", "3600");

        response.setHeader("Access-Control-Allow-Headers", "x-requested-with,Authorization");

        response.setHeader("Access-Control-Allow-Credentials", "true");

        String method = request.getMethod();

        if(method.equalsIgnoreCase("OPTIONS")){

            servletResponse.getOutputStream().write("Success".getBytes("utf-8"));

        }else{

            filterChain.doFilter(servletRequest, servletResponse);

        }

    }

 

    @Override

    public void destroy() {

 

    }

}

　2、web.xml配置

<filter>

    <filter-name>corsFilter</filter-name>

    <filter-class>xxx.xxx.CorsFilter</filter-class>

</filter>

<filter-mapping>

    <filter-name>corsFilter</filter-name>

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

</filter-mapping>

三、配置跳过登录权限验证，进行接口访问

1、在spring-context-shiro.xml配置文件中，进行一下配置
