websphere5.1+spring2.0+struts2+hibernate3搭建总结

最近搭建了一个websphere5.1+spring2.0+struts2+hibernate3的框架，因为jdk1.4加websphere5.1环境中间碰到一些问题，网上的解决方案也不全，今天搞了一整天总算搞定了，现与大家分享下。

开发工具myeclipse6，先在tomcat4 jdk4上测试，然后部署到websphere5.1上测试通过。

步骤：

1.设置编译环境为jdk1.4

2.把自己代码中所有1.5的特性都改成1.4

3.web.xml改成servlet2.3规范的

4.lib包不要配缺了就行

spring和hibernate的包都是jdk1.4编译的，不需要修改，其中cglib用的是cglib-nodep-2.1_3.jar而不是cglib-2.1_3.jar

struts2由于是jdk1.5编译的需要用retrotranslator转换，工具在struts2目录下的backport目录中，struts2-core-j4-2.0.11.1.jar和xwork-j4-2.0.4.jar已经转好了，再自己转个struts2-spring-plugin-j4-2.0.11.1.jar就可以了，最后把backport-util-concurrent-3.0.jar，retrotranslator-runtime-1.2.2.jar和你转好的包扔到lib目录下，原来的删除。

这方面网上资料还是蛮多的，不明白的可以查找下。

5.websphere5.1兼容性问题

当你成功完成上述步骤后tomcat4已经可以跑了，然后部署到websphere5.1如果没有错误的话可以运行而且后台不报错，但是页面上报XXX.action路径找不到，这个花了我好多时间才搞定，网上也没找到具体解决方案。

原因：

DefaultActionMapper类中的getUri方法：

String getUri(HttpServletRequest request) {
		// handle http dispatcher includes.
		String uri = (String) request
				.getAttribute("javax.servlet.include.servlet_path");
		if (uri != null) {
			return uri;
		}

		uri = RequestUtils.getServletPath(request);
		//System.out.println("url==========="+uri);
		//old:if (uri != null && !"".equals(uri)) {
		if (uri != null && uri.length() > 1) {
			return uri;
		}

		uri = request.getRequestURI();
		return uri.substring(request.getContextPath().length());
	}

 发现上面注释掉的那句：

//System.out.println("url==========="+uri);

输出为"/",实际为"/XX/XX.action"看来是uri解析错误，猜想可能是

RequestUtils.getServletPath(request);

这个方法有bug，结果发现源代码没提供，所以只能在外层方法中改下了,重写了个过滤器。改完后成功运行。

解决方案如下，添加2个类

DefaultActionMapperCompaWebsphere51(修改了getUri后的判断)

}

 修改web.xml中原来的struts2的filter类

<filter>
        <filter-name>struts2</filter-name>
        <filter-class>
            org.apache.struts2.dispatcher.FilterDispatcherCompaWebsphere51
        </filter-class>
    </filter>

之后就可以放在tomcat和websphere5.1上运行了。

本文只说明了遇到的一些问题的解决方案，如何配置struts2或spring或hibernate可以参考官方资料。
