JSP中使用EL表达式 ieELIgnoed问题
[html]
<%@ page language="java" contentType="text/html; charset=UTF-8" pageEncoding="UTF-8" isELIgnored="false"%>
<%@ taglib uri="https://java.sun.com/jsp/jstl/core" prefix="c" %>
<c:out value="${param.para1}" default="hello world">
在apache-tomcat-6.0.35-src中可以看到这一点:
[java]
protected String[] generateJava() throws Exception {
String[] smapStr = null;
long t1, t2, t3, t4;
t1 = t2 = t3 = t4 = 0;
if (log.isDebugEnabled()) {
t1 = System.currentTimeMillis();
}
// Setup page info area
pageInfo = new PageInfo(new BeanRepository(ctxt.getClassLoader(),
errDispatcher), ctxt.getJspFile());
JspConfig jspConfig = options.getJspConfig();
JspConfig.JspProperty jspProperty = jspConfig.findJspProperty(ctxt
.getJspFile());
/*
* If the current uri is matched by a pattern specified in a
* jsp-property-group in web.xml, initialize pageInfo with those
* properties.
*/
if (jspProperty.isELIgnored() != null) {
pageInfo.setELIgnored(JspUtil.booleanValue(jspProperty
.isELIgnored()));
}
