我在运行我的应用程序时收到以下信息:
The listener "com.sun.faces.config.ConfigureListener" is already configured for this context. The duplicate definition has been ignored.
我想知道这种错误的原因是什么？
我有一个映射到Long属性的输入文本.
private Long length;
<h:inputText value="#{bean.length}" />
当我在输入文本中输入非数字时,我收到以下转换错误:
myForm:myField:'someText'必须是由一个或多个数字组成的数字.
我想知道如何自定义此消息:
长度必须是大于零的数字.
在我的web.xml中,我想从属性文件中读取欢迎文件,例如:
<welcome-file-list>
<welcome-file>${home.page}</welcome-file>
</welcome-file-list>
我有propertyPlaceholderConfigurer配置:
<bean id="propertyPlaceholderConfigurer"
class="org.springframework.beans.factory.config.PropertyPlaceholderConfigurer">
<property name="locations">
<list>
<value>classpath:messages/application.properties</value>
</list>
</property>
</bean>
应该在web.xml中添加额外的参数,还是需要定义另一个bean或者是什么？
另外我在web.xml的同一级别上有另一个xml文件(在WEB-INF direclty下)我能以同样的方式从属性文件中读取吗？
请指教.

我有三个实体:

我得到一个问题,如果我有不同类型的鸟类,如何在OOP中代表它们,我说我将为鸟类制作另一个类别,不同类型的鸟类将扩展它.
请把你的想法告诉我.
我为登录页面做了一个成功的selenium测试用例,用户输入正确的用户名和密码然后点击登录转发到主页,问题是当我在测试类中更改密码时,测试总是成功我不要我知道为什么.
这是测试类:
public class LoginTest extends TestCase {
private WebDriver driver;
private String baseUrl;
private StringBuffer verificationErrors = new StringBuffer();
@Before
public void setUp() throws Exception {
driver = new FirefoxDriver();
baseUrl = "http://localhost:8080";
}
@Test
public void testLoginClass() throws Exception {
driver.get(baseUrl + "/MyAPP/login");
driver.manage().timeouts().implicitlyWait(60, TimeUnit.SECONDS);
driver.findElement(By.id("j_username")).clear();
driver.findElement(By.id("j_username")).sendKeys("1");
driver.findElement(By.id("j_password")).clear();
driver.findElement(By.id("j_password")).sendKeys("wrong password");
driver.findElement(By.id("loginBtn")).click();
}
@After
public void tearDown() throws Exception {
driver.quit();
String verificationErrorString = verificationErrors.toString();
if (!"".equals(verificationErrorString)) {
fail(verificationErrorString);
}
}

<bean id="propertyPlaceholderConfigurer"
class="org.springframework.beans.factory.config.PropertyPlaceholderConfigurer">
<property name="locations">
<list>
<value>classpath:messages/application.properties</value>
<value>file:${My_ENV_VAR}/*.properties</value>
</list>
</property>
<property name="ignoreResourceNotFound" value="true" />
<property name="searchSystemEnvironment" value="true" />
<property name="systemPropertiesModeName" value="SYSTEM_PROPERTIES_MODE_OVERRIDE" />
</bean>
我有一个新的环境变量命名,My_ENV_VAR=C:\Program Files\My Folder\props.properties
但在停止和启动应用程序时,没有设置变量的值,任何想法为什么？
更新:要求
我想从文件系统上的外部属性文件中读取applicationContext.xml中的hibernate属性(url,username,password),其路径存储在环境变量中.
