Development environment eclipse, myEclipse local tomcat debug release bad feelings maven project encountered

　　Before using myEclipse Web Project has been developing the project, deployed by myEclipse local tomcat fairly well, but there is a problem, myEclipse the Java Compiler only supports 1.7, but requires at least spring boot is jdk1.8, so give up myEclipse into eclipse, As for the idea back then. Here to talk about the development environment eclipse, myEclipse local tomcat debug release bad feelings maven project encountered.

　　(1) myEclipse deployed to the tomcat maven project not identify the project, can not be deployed

　　Solution: Right Project Properties, find myEclipse-> Project Facets check on the Dynamic Web Module, other hook is uncertain whether, by default it first, as shown:

　　Solution: Right Project Properties, find Project Facets check on the Dynamic Web Module, whether the other hook is uncertain, according to the first default of it, as

　　Possible cause 1: Not Set catalog publishing, you need to set the following figure:

　　Possible Cause 2: No Click publish button, as shown below (newly revised code does not compile to the next tomcat, also need to click this button)

　　The way I deal with is: can a normal display items .project file copy, to replace the project. A normal attachment:

　　解决方法：右键项目Properties，找到Deployment Assembly设置java、resources、webapp、Maven Dependencies 如下：
