Modify the Eclipse project to support JPA tools
http://blog.sina.com.cn/s/blog_484d87770100u4nm.html
I created a web project with Eclipse, and I want to generate database entity beans for the project through JPA Tools of eclipse, but I can't see the JPA Tools option in the right-click menu.
So recruit a similar project (you can right-click to see JPA Tools), check the .setting/org.eclipse.wst.common.project.facet.core.xml file under its project path,
It is found that there is such a sentence "<installed facet="jpt.jpa" version="1.0"/>" in the <faceted-prject> tag, so copy this sentence to the corresponding file of the new project. refresh the project,
After right-clicking again, I saw the JPA Tools I wanted to see.

Or directly to the right side of the project, select properties--" project facets --> check jpa, if not, install the jpa plugin and then do so
