JSP DEBUG
以下表达式在Tomcat 7上运行没有异常，发布到 JBossEAP 6.2后总是报非法参数异常，究其原因是Tomcat EL parser支持可变参数，JBossEAP 6.2不支持。
${currentUser.isPermitAny("SUPPLIER_UPDATE_BASIC","SUPPLIER_UPDATE_INVOICE","SUPPLIER_UPDATE_PAYMENT")}'
public boolean isPermitAny(String... permissions){
boolean[] ps = SecurityUtils.getSubject().isPermitted(permissions);
for (boolean b : ps) {
if(b) return true;
}
return false;
}
解决方法
<%@ taglib prefix="fn" uri="http://java.sun.com/jsp/jstl/functions" %>
${currentUser.isPermitAny(fn:split("SUPPLIER_UPDATE_BASIC,SUPPLIER_UPDATE_INVOICE,SUPPLIER_UPDATE_PAYMENT",","))}
public boolean isPermitAny(String[] permissions){
boolean[] ps = SecurityUtils.getSubject().isPermitted(permissions);
for (boolean b : ps) {
if(b) return true;
}
return false;
}
或者
${currentUser.isPermitAny("SUPPLIER_UPDATE_BASIC,SUPPLIER_UPDATE_INVOICE,SUPPLIER_UPDATE_PAYMENT")}
public boolean isPermitAny(String permissions){
boolean[] ps = SecurityUtils.getSubject().isPermitted(StringUtils.split(permissions, ","));
for (boolean b : ps) {
if(b) return true;
}
return false;
}
