Tomcat7.0.59 cannot parse an EL expression

Tomcat7.0.59 solution for El Expressions cannot be resolved 1. Corporate server in the transition from Windows to Windows, Tomcat from 6 to 7, in the process of conversion encountered New.title can not be resolved, but the previous TOMCAT6 can be used normally. After finding the data, we found that TOMCAT7 has new features .

Tomcat 7 has strict syntax requirements for El expressions, such as "${new.title}" which causes parsing errors due to the inclusion of the keyword new. \

This time for us to modify the configuration file, ignore the keyword settings:

Modifies the Tomcat attribute, ignoring the keyword check for El expressions. Modify the $catalina_base/conf/catalina.properties file and add the Org.apache.el.parser.skip_identifier_check=true option.

2. Also modify the project's Web.xml file, the red part is removed:
