Cors Cross domain request, configure Access-control-allow-origin: "*", Invalid solution __java related

Because the application needs Cross-domain request data, the blogger in JDK8, Tomcat7.0 cors can configure Access-control-allow-origin: "*", but I did not take effect following the document configuration, once suspected that the problem is tomcat or JDK, In the end, Web.xml is loaded in the same order as in the past. Solution: Is the filter location problem, you put the whole into the first filter position is OK. Give the Web.xml:

<?xml version= "1.0" encoding= "UTF-8"?>
