spring报错 mismatched input 'gt' expecting EOF

Question

代码如下：
<?xml version="1.0" encoding="UTF-8"?>
xmlns:p="http://www.springframework.org/schema/p"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xmlns:util="http://www.springframework.org/schema/util"
xsi:schemaLocation="http://www.springframework.org/schema/beans
http://www.springframework.org/schema/beans/spring-beans-3.0.xsd
http://www.springframework.org/schema/util
http://www.springframework.org/schema/util/spring-util-3.0.xsd">




在使用#{100 gt 80}也就是100>80这一代码时报错，异常如下：
