Struts2 - JSP EL - 连接似乎不起作用 [英] Struts2 - JSP EL - Concatenation doesn't seem to work

问题描述

试图弄清楚这个问题很长时间......

Trying to figure out this issue for a long time...

我正在使用来自对象的值设置一个变量.

I am setting a variable with a value from an Object.

<s:set name="bodyText" value='First Name "myObject.name"'/>

并尝试通过以下方式打印它..这些都不起作用.

and trying to print it in the following ways.. None of these works.

"${bodyText}"
"<s:property value="#bodyText" />"
"${#bodyText}"
"%{bodyText}"
"%{#bodyText}"

不确定问题出在哪里

我也尝试了以下方法:

Not sure the problem is with

I tried the following as well:

<s:set name="bodyText" value='First Name "${myObject.name}"'/>

但它不起作用.

推荐答案

value属性应该是一个对象.OGNL 使用引号来分隔字符串对象，其他引号应该被转义.

The value attribute should be an object. OGNL uses quotes to delimit a string object, other quotes should be escaped.

并使用 var 属性作为变量名.

And use var attribute for variable name.

<s:set var="bodyText" value="'First Name "myObject.name"'"/>
<s:property value="bodyText" />
