小编San*_*eep的帖子

我安装了

• Java 1.7
• Eclipse Juno
• 从Eclipse Market安装 - Maven Integration for Eclipse WTP(aka m2e-wtp),m2e-apt,Spring IDE,Spring Tool Suite™(STS)
• 已定义M2_HOME为安装Maven的目录.PATH更新为%M2_HOME%/bin

我正在使用Windows XP.

我能够创建一个Maven项目但是当尝试添加依赖项(select pom.xml- Dependencies - Add)时,输入artifactId的" Enter groupId, artifactId or sha1 prefix or pattern"不会显示.假如我输入"springframework",它只反映本地安装的jar并且不通过互联网搜索.此外,如果我检查Maven存储库(由Windows选择 - 显示视图 - 其他 - Maven - Maven存储库),则不会在全局存储库中显示任何内容(http://repo.maven.apache.org/maven2).

如果我手动将所需内容artifactID放入pom.xml然后更新maven,则会下载所需的jar.

我正在我的家用电脑上工作,我没有任何代理,并在本地m2设置中设置了以下(C:\Documents and Settings\Sandy\.m2\Settings.xml)

你能告诉我,我需要做什么设置才能使用添加依赖项选项添加输入的工件吗？

提前致谢

首先,我是Spring MVC世界的新手.

我做了一个简单的程序,其中Spring MVC将处理GET请求并设置一个名为"message"的变量.此变量应在JSP中显示设置值,但未按预期执行.代码正在编译并运行正常.能告诉你,这里做错了什么？

我做了一个简单的程序,但得到了以下错误.我正在使用Eclipse Kelper和Tomcat 7.0.尝试了很多东西,但没有什么对我有用:(
