Our company is using the SPRINGMVC + MyBatis Framework, the original morning operation of the project can be normal operation, the background page operation is also normal, the afternoon operation of the background user management to add staff data is also very normal display, the controller inside the change method to normal execution, the background no error, I add System.out.println ("----------") to the method, but there is no output after the method is run, this is the whole project! I entered BuildPath--->configure buildpath--->libiaries---> View jar package, found that some jars are red, possibly lost jar packets, jar conflicts, So solve the problem in time! Restart Tomcat, send line tomcat--->class file compiles successfully!
2.SVN Update Project Be sure to check buildpath--->configure buildpath--->libiaries---> View jar Package
Whether there is a need to add or remove
3. You can clean,clean tomcat work directory at any time
