<script type="text/javascript">

function back(){
history.go(-1);
}

//详细信息
function findByIdFromshow(form,id){
document.getElementById('filterOfferDetailedId').value=id;
alert(id);
var url='<s:url action="show" namespace="/quote"/>';
form.action = url;
form.submit();
}
</script>

</head>

这里是Action层：

package com.shhelian.app.action.chance;

import java.text.SimpleDateFormat;

import org.apache.commons.lang.StringUtils;
import org.apache.log4j.Logger;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.context.annotation.Scope;
import org.springframework.stereotype.Component;

import com.shhelian.app.model.QuoteDetailed;
import com.shhelian.app.model.SellChance;
import com.shhelian.app.model.SellOrder;
import com.shhelian.app.service.chance.QuoteDetailedService;
import com.shhelian.modules.orm.PaginationSupport;
import com.shhelian.modules.web.struts2.BaseCRUDAction;

@Component("quoteDetailed")
@Scope("prototype")
public class QuoteDetailedAction extends BaseCRUDAction<QuoteDetailed> {

static Logger logger = Logger.getLogger(QuoteDetailedAction.class.getName());

@Autowired
private QuoteDetailedService entityService;

// model
private QuoteDetailed entity;

private String filterOfferDetailedId;

private String filterProductName;

@Override
protected void prepareModel() throws Exception {
logger.debug("==========> prepareModel");
if (StringUtils.isNotBlank(filterOfferDetailedId)) {
System.out.println(filterOfferDetailedId);
entity = entityService.findById(filterOfferDetailedId);
} else {
entity = new QuoteDetailed();
}
}

/**
* 集合列表
*/
@Override
public String list(){
try{
PaginationSupport<QuoteDetailed> ps = entityService.findPage(
getPagination().getPageSize(),
getPagination().getStartIndex(),
filterProductName);
setPagination(ps);
return RELOAD;
}catch (Exception e) {
e.printStackTrace();
}
return ERROR;
}
/**
* 详细信息
*/
@Override
public String show(){
logger.debug("=====================" + filterOfferDetailedId);
System.out.println("***************************" + filterOfferDetailedId);
entityService.findById(filterOfferDetailedId);
return RELOAD;
}

/**

*/
@Override
public String insertSubmit() throws Exception {
logger.debug("==========> insertSubmit");
try {
entityService.save(entity);
return RELOAD;
} catch (Exception ex) {
ex.getStackTrace();
return ERROR;
}
}

@Override
public QuoteDetailed getModel() {
return entity;
}

public String getFilterOfferDetailedId() {
return filterOfferDetailedId;
}

public void setFilterOfferDetailedId(String filterOfferDetailedId) {
this.filterOfferDetailedId = filterOfferDetailedId;
}

public String getFilterProductName() {
return filterProductName;
}

public void setFilterProductName(String filterProductName) {
this.filterProductName = filterProductName;
}

}

页面报错：

java.lang.IllegalArgumentException: id to load is required for loading
org.hibernate.event.LoadEvent.<init>(LoadEvent.java:74)
org.hibernate.event.LoadEvent.<init>(LoadEvent.java:56)
org.hibernate.impl.SessionImpl.get(SessionImpl.java:840)
org.hibernate.impl.SessionImpl.get(SessionImpl.java:836)
org.springframework.orm.hibernate3.HibernateTemplate$1.doInHibernate(HibernateTemplate.java:531)
org.springframework.orm.hibernate3.HibernateTemplate.doExecute(HibernateTemplate.java:419)

错误的原始是我Action层里的Id为Null，可是我页面明明获取到Id了 alert()；了下。 Id是有值的，为什么到Action层就为Null ，求大神指教哦！

有的。在Action层最下面，问题我已经解决了。楼下的那个仁兄给出的答案是正确的。

因为你的id没有被form包括，把这一行
<s:hidden id="filterOfferDetailedId" name="filterOfferDetailedId" value=""/>
放到form中就可以了

蒽蒽、是的。我刚发完帖子就找到错误原因。呵呵。找到错误原因后我第一时间就把解决方法公布出来了。还是很谢谢你。
