idea无报错但显示空白页面是什么原因?

80

####idea2018.3 自带的tomcat JDK1.8
引入的eclipse maven项目 编译和启动都成功了 没有报错
然后进入localhost8080端口 显示空白页面 控制台报了如下信息:

2019-07-26 14:31:41.420 [http-nio-8080-exec-1] INFO  o.a.c.core.ContainerBase.[Tomcat].[localhost].[/] - Initializing Spring FrameworkServlet 'dispatcherServlet'

直接在网址输入http://localhost:8080/login 报如下:

####**不知道是什么原因,是tomcat的问题吗?还是拦截器的原因?可是这个是从svn拉下来的,同事的eclipse完美运行**

# 页面默认前缀目录
spring.mvc.view.prefix=/WEB-INF/page/
# 响应页面默认后缀
spring.mvc.view.suffix=.jsp

    svn获取,同事的没问题,应该就不是代码问题,应该是配置问题。
    建议,删除项目,重新从svn获取。然后配置。
    选择对应项目的jdk版本,注意idea输出文件的位置,和eclipse有区别。maven第一次下载过,第二次应该很快,
    然后一步一步配置,然后Artifatcs 。然后配置tomcat。
    然后注意几个地方:图片说明
    建议还是用自己的tomcat,我遇到很多坑,就是这个问题。弄了几天。有时候还会昨天完美运行,今天就挂了。

    HttpRequestMethodNotSupportedException: Request method 'GET' not supported
    项目的login发起的请求为'GET' 而你后台对应的login方法请求估计是POST从而请求不到后台的login方法导致报错
    项目的login发起的请求'GET'改为POST即可
