Eclipse上的tomcat服务器：如何随意使tomcat服务器重新加载项目上下文

Question

I am writing a simple restful APT on Eclipse neon 3 and tomcat 7 (tomcat 9 does not work either). But Tomcat server could not update after I save my java code and run my project on the server. I noticed that only when the server reload the context like below, it executed the updated version of java files:

Sep 04, 2017 8:20:35 PM org.apache.catalina.core.StandardContext reload
INFO: Reloading Context with name [/messenger] has started
Sep 04, 2017 8:20:37 PM org.apache.catalina.startup.TldConfig execute
INFO: At least one JAR was scanned for TLDs yet contained no TLDs. Enable debug logging for this logger for a complete list of JARs that were scanned but no TLDs were found in them. Skipping unneeded JARs during scanning can improve startup time and JSP compilation time.
Sep 04, 2017 8:20:38 PM org.apache.catalina.core.StandardContext reload
INFO: Reloading Context with name [/messenger] is completed

The problem is how to make tomcat server reload project context at will so that I can reload the context whenever I want.

I have tried the following options, but all failed:

1) build project + run on sever

2) restart server

3) restart server on debug mood.

Also, tomcat server.xml reloadable property in Context is true be default.

Thanks a lot!

Check your eclipse properties. Go to your project properties --> check deployment assembly and java build path.
