@PostConstruct Weblogic上标注10.3.4不会被调用 [英] @PostConstruct annotation on Weblogic 10.3.4 not being called

问题描述

（这似乎的重复<一href=\"http://stackoverflow.com/questions/5862085/weblogic10-3-ignores-postconsturt-method\">Weblogic10.3忽略@PostConsturt方法。，但有小细节并没有回答）。

(This seems a duplicate of Weblogic10.3 ignores @PostConsturt method., but that has little details and is not answered).

我有这样一个ManagedBean：

I have a ManagedBean like this:

public class TestBean {
    private String greeting = "Hello, World!";

    public TestBean() {
    }

    public String getGreeting() {
      System.out.println( "getGreeting called, returning " + this.greeting );
      return greeting;
}

public void setGreeting( String message ) {
      this.greeting = message;
}


    @PostConstruct
    public void prepareSomething() {
        System.out.println( "\n\nPostConstruct called.\n\n" );
        this.greeting += " (PostConstruct was called)";
    }
}

在我的XHTML，我只是豆消息：＃{TestBean.greeting} 。访问页面的时候，但是，该方法不叫，什么我得到的是

and in my xhtml, I have simply Bean Message: #{TestBean.greeting}. When accessing the page, however, the method is not called, and what I get is

Bean Message: Hello, World!

而不是预期的

Bean Message: Hello, World! (PostConstruct was called)

Console会显示系统输出的从 getGreeting（）方法，而不是从 prepareSomething（）：

INFO: Added Library from: zip:/data/java/wl1034/user_projects/domains/wlrep1034/autodeploy/PCTest.ear/PCTest.war/WEB-INF/lib/jsf-facelets.jar!/META-INF/jstl-fn.taglib.xml
getGreeting called, returning Hello, World!
2011-05-12 10:36:11,720 DEBUG org.richfaces.skin.SkinFactoryImpl - Create new Skin instance for name DEFAULT 

进一步信息：我使用JSF 1.2（使用的Weblogic 10.3.4的 MW_HOME /普通/部署-库/ JSF的1.2.war罐子/ WEB-INF / lib目录），Facelets的1.1.14，RichFaces的3.3.2。我对 WEB-INF / lib目录下的jar ：

Further info: I am using JSF 1.2 (using the jars from Weblogic 10.3.4's MW_HOME/common/deployable-libs/jsf-1.2.war!/WEB-INF/lib), Facelets 1.1.14, RichFaces 3.3.2. I have the following jars on WEB-INF/lib:

commons-beanutils-1.7.0.jar
commons-digester-1.8.jar
commons-logging-1.1.1.jar
glassfish.jsf_1.0.0.0_1-2-15.jar
glassfish.jstl_1.2.0.1.jar
javax.jsf_1.1.0.0_1-2.jar
jsf-facelets.jar
log4j-1.2.16.jar
richfaces-api-3.3.2.SR1.jar
richfaces-impl-3.3.2.SR1.jar
richfaces-ui-3.3.2.SR1.jar
SimpleJSF.jar
wls.jsf.di.jar

我曾尝试拨打/删除注释-api.jar文件为好，相同的症状。

我可能会在必要时发布的其他文件。

I may post other files if necessary.

推荐答案

我不使用Weblogic的，但如果我没有错，Weblogic的已经附带了自己的JSTL / JSF库。所以，你不需要自己在所有提供给他们。

I don't use Weblogic, but if I am not wrong, Weblogic already ships with its own JSTL/JSF libraries. So you don't need to supply them yourself at all.

但是，如果我错了，Weblogic的不跟他们出货，那么这些库看起来不完全正确。究竟那些是什么版本？

But if I am wrong and Weblogic don't ship with them, then those libraries doesn't look quite right. What versions exactly are those?

glassfish.jsf_1.0.0.0_1-2-15.jar
glassfish.jstl_1.2.0.1.jar
javax.jsf_1.1.0.0_1-2.jar

的 @PostConstruct 适用于JSF 1.2或更高版本而已。你可以在这里下载 JSF 1.2 。它存在两个JAR文件

The @PostConstruct works on JSF 1.2 or newer only. You can download JSF 1.2 here. It exist of two JAR files

jsf-api.jar
jsf-impl.jar

您只需要确保你的 faces-config.xml中声明符合JSF 1.2规范并且也是的web.xml 声明符合至少的Servlet 2.5规范。

You only need to ensure that your faces-config.xml is declared conform JSF 1.2 specification and also that web.xml is declared conform at least Servlet 2.5 specification.

最后，JSTL库应该这个。

Finally, the JSTL library should be this one.
