如何访问Java bean的非getter / setter方法

Question

I have an xhtml page that gets values from a java bean:

<h:dataTable value="${myBean.getAccounts}" var="account">
        <h:column>
            <f:facet name="header">Account ID</f:facet>
            #{account.id}
        </h:column>
        <h:column>
            <f:facet name="header">Account Name</f:facet>
            #{account.name}
        </h:column>

</h:dataTable>

The problem is that when I run this on a Tomcat 7 server, I get an error: getAccounts is not a myBean property. The java class's getAccounts method is a standalone method that returns some results.

Is there no way I can call this method?

Any help is appreciated.

Thanks!

Answer 1

The property name is accounts , not getAccounts . getAccounts is a getter that returns the property accounts

Answer 2

EL将带有get / set前缀的任何方法都视为属性，因此，如果使用任何方法调用该方法，则可以省略get / set部分。

Answer 3

Jeff's answer is correct. Just some additional info:

Your method is called getAccounts() but in EL you need to say #{mybean.accounts}

There is a good complete example of using ah:dataTable here
