Just saw online about solving Ognl. Ognlexception:target is null for setProperty (NULL, "authorized", [Ljava.lang.string;@1d7ce3) error, see a few found wrong, breakpoint debugging, Resolves the problem. Share to everyone:
Resolve similar to OGNL. Ognlexception:target is null for setProperty (NULL, "authorized", [Ljava.lang.string;@1d7ce3) error, which is generally caused by a value not being taken. breakpoint debugging to see which value is empty, and then modify the next OK. The following is my own situation: when you add an action, you get a variable value that is redefined. The name value in the JSP is the entity class. Value, ignore the error, or change the value of the action to the entity class. Value, or change the value of the JSP to the value of the variable redefined in the action, so it's OK.
