eclipse JavaWeb ApplicationContextjava
1.在服务器上运行TestHelloServlet.java时报错。该文件主要是经过Web服务器实例化ApplicationContext容器。服务器
2.案例代码来自书籍《JavaEE框架整合开发入门到实战——Spring+SpringMVC+MyBatis》P14(2.2.2 ApplicationContext)框架
1.Resource '/Servers' does not exist.eclipse
2.'Starting Tomcat v9.0 Server at localhost' has encountered a problem.
Port 8080 required byTomcat v9.0 Server at localhost is already in use. The server may already be running in another process, or a system process may be using the port. To start this server you will need to stop the other process or change the portnumber(s).编辑器
1.删除原有Server,新建Server
2.修改端口
3.重启eclipse学习
1.在服务器上运行TestHelloServle As--Run on Server)ui
2.报错:this
Resource '/Servers' does not exist.
![]()
3.删除Server
1)删除底部Server面板的全部服务器;
2)删除左边Server文件夹
若是项目较为重要,建议备份一下Server文件夹。个人项目只是一些案例的学习,不过重要,因此直接删除
4.新建Server(在对应项目上右击,好比Ch1项目,而后依次选择New--Other)
spa
5.启动底部Server面板的服务器
6.报错.net
'Starting Tomcat v9.0 Server at localhost' has encountered a problem.
Port 8080 required byTomcat v9.0 Server at localhost is already in use. The server may already be running in another process, or a system process may be using the port. To start this server you will need to stop the other process or change the portnumber(s).
能够看出缘由是端口号8080被占用。解决方法有两个:①终止其余使用了端口8080的进程;②修改Tomcat的端口。
经分析,发现是电脑上的Apache Httpd使用了端口号8080(安装目的主要是为PHP所用,在Appserv下)。我决定直接修改Tomcat端口
7.打开左侧Servers文件夹所在目录,用文本编辑器打开其下的server.xml文件,搜索相关文本,以修改端口。其中搜索内容为:
<Connector connectionTimeout=
8.(务必)重启eclipse
9.启动Servers面板的服务器
10.在服务器上运行TestHelloServlet.java。(Run As--Run on Server)
11.完成。
