- @ResponseBody
- Public list<edittimeout> List () {
- list<edittimeout> list = Editimpl.selectall ();
- return list;
- }
Request, debug trace list is the return value no problem, but the foreground page reports the following error:
Java code
- Response Status: 406 (not acceptable)

Cause of the cause:
Because the @responsebody is set, it is wrong to convert the object to JSON format, without the jar package for the conversion dependency.
Workaround:
Join the dependent Jar,jackson-core-asl-1.9.12.jar,jackson-mapper-asl-1.9.12.jar problem resolution.
