我正在使用Jdbctemplate从db中检索单个String值.这是我的方法.
public String test() {
String cert=null;
String sql = "select ID_NMB_SRZ from codb_owner.TR_LTM_SLS_RTN
where id_str_rt = '999' and ID_NMB_SRZ = '60230009999999'";
cert = (String) jdbc.queryForObject(sql, String.class);
return cert;
}
在我的方案中,完全可能不会得到我的查询,所以我的问题是如何解决以下错误消息.
EmptyResultDataAccessException: Incorrect result size: expected 1, actual 0
在我看来,我应该回到null而不是抛出异常.我怎样才能解决这个问题？提前致谢.
我在Parcelable下面创建了一个对象,我的对象包含一个ListProducts.在我的构造函数中,如何处理重新创建我Parcelable的List？
我检查了包裹中可用的所有方法,所有可用的方法都是readArrayList(ClassLoader).我不确定这是不是最好的方法,你的建议真的很值得赞赏.
public class Outfits implements Parcelable {
private String url;
private String name;
private List<Product> products;
public String getUrl() {
return url;
}
public void setUrl(String url) {
this.url = url;
}
public String getName() {
return name;
}
public void setName(String name) {
this.name = name;
}
public List<Product> getProducts() {
return products;
}
public void setProducts(List<Product> products) {
this.products = products;
}

我刚刚在市场上发布了我的第一个应用程序,并将我的名字放在开发人员名称下,而不是我的公司名称,这应该是它应该是的.然后我将开发人员名称更新为我的公司名称,但更改似乎没有更新.
有谁知道我什么时候可以看到更改名称？
我正在尝试直接实例化JMS资源而不使用JNDI到REMOTE HORNETQ.
我在Eclipse IDE中运行我的测试代码.设置我的类路径以使用HornetQ 2.2.5库.
目标HornetQ是版本2.1.2.Final,我认为他们应该向后兼容,也许我错了？
好的,所以我已经阅读了在线文档,并按照连接到远程JMS服务器的示例而不使用JNDI.我继续得到以下异常.我不知道我错过了什么,但我相信我已经正确设置了一切.有人可以指出我在这里失踪了吗？提前致谢.
JMSException:无法创建会话工厂

TextMessage …我有一个Fragment活动,左边有一个ListFragment,右边有一个带有WebView的Fragment.功能正常但我想在网页完成加载时显示一个显示"正在加载..."的进度对话框.我怎样才能完成这个看似微不足道的任务呢？
以下是我的代码:

ArticleListFragment.OnArticleSelectedListener {
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.articlelist_fragment);
}

Intent showContent = new Intent(getApplicationContext(),
ArticleViewerActivity.class);
showContent.setData(Uri.parse(contentLink));
startActivity(showContent);
} else {
viewer.updateUrl(contentLink);
}
}
