这个tomcat7-maven-plugin:run插件可以实现吗？我很难找到正确的语法来让它发挥得很好.当我运行maven命令来运行它时,它只运行它在项目层次结构中找到的第一个命令.如果我使用<fork>true</fork>或显然从不同的终端运行它们然后我得到"java.net.BindException:地址已在使用:8080".

如何在现有的tomcat Web应用程序上实现SSO

我有一个tomcat 7设置,其上部署了oldApp.war和newApp.war.两个应用程序共享数据库上用户的相同登录凭据.

我可以分别使用https://localhost/oldApp和访问应用程序https:localhost/newApp.

我的oldApp是一个Spring MVC java应用程序,当用户登录到oldApp时,我希望有一个链接,将用户带入newApp而不需要登录凭据.

我想知道如何实现SSO来做到这一点.我最好不要运行任何外部服务来处理这个问题.

提前致谢.

如何在Spring Boot中使用Tomcat JNDI JDBC数据源

我有一个Spring启动应用程序,并希望作为WAR部署到Tomcat 7.作为其中的一部分,我需要将配置保留在WAR之外,以便我可以将相同的战争部署到我的舞台和生产服务器并让它获取通过配置mysql连接.

为此,我想配置我的Spring Boot应用程序,以使用在Tomcat实例中配置为JNDI数据源的mysql连接.

弹簧靴可以这样做,如果是这样的话怎么样？

另外,在Spring 4中这很容易做到,而不需要使用基于xml的配置.

我无法使用断点进行调试

当我尝试放置断点并调试我的项目时,我在SpringSource Tool Suite(eclipse)中收到一条奇怪的错误消息,所以在这种情况下,当我启动Tomcat进行调试时,它会显示以下错误消息:"无法安装断点在bus.GenBUS $$ EnhancerByCGLIB $$ 749137d3中由于缺少行号属性.修改编译器选项以生成行号属性.原因:缺少行号信息"

但是我已经控制好了,在Preferences - > Java - > Compiler部分(添加行号attr ...)中一切正常.我的项目是Spring MVC项目......有什么建议吗？
