我正在開發一個項目（我想說「隨機」，因爲它有時會啓動，並且在服務器重新啓動後，它顯然沒有任何理由拋出異常）關於bean轉換服務的問題。當啓動服務器時，Spring bean拋出異常
Exception encountered during context initialization - cancelling refresh attempt

它似乎無法找到類，但類實際上是在project.formatter.DateFormatter
這裏是spring-mvcconfig.xml豆：
<bean id="conversionService"
class="org.springframework.format.support.FormattingConversionServiceFactoryBean">
<property name="formatters">
<set>
<bean class="project.formatter.DateFormatter">
<constructor-arg type="java.lang.String" value="dd/MM/yyyy" />
</bean>
</set>
</property>
</bean>
這裏的DateFormatter等級：
package project.formatter;
import java.text.ParseException;
import java.text.SimpleDateFormat;
import java.util.Date;
import java.util.Locale;
import org.springframework.format.Formatter;
public class DateFormatter implements Formatter<Date> {
private String datePattern;
private SimpleDateFormat dateFormat;
public DateFormatter(String datePattern) {
this.datePattern = datePattern;
dateFormat = new SimpleDateFormat(datePattern);
dateFormat.setLenient(false);
}
public String print(Date date, Locale locale) {
return dateFormat.format(date);
}
public Date parse(String s, Locale locale) throws ParseException {
try {
return dateFormat.parse(s);
} catch (ParseException e) {
// the error message will be displayed when using <form:errors>
throw new IllegalArgumentException(
"invalid date format. Please use this pattern\""
+ datePattern + "\"");
}
}
}
它給出了同樣的錯誤，以誰的工作與我的其他人，但他們只需要做一個maven clean來解決問題，對我來說是行不通的這種方法。 我做了一個乾淨的，然後重新啓動服務器，我得到了同樣的錯誤，唯一的辦法是重新從svn結帳，它工作了一段時間，然後開始給我這個問題了。 我不是在那個班上工作，我也沒有編輯springmvc-config.xml 我不知道該如何解決這個問題。 我檢查了springmvc-config,web.xml，我應該在哪裏嘗試解決這個問題？ 謝謝大家的幫助。編輯： 它似乎給每個其他豆的錯誤。我評論了conversionService bean，它沒有提供更多的異常，並拋出bean dataSource的異常，評論這樣的bean，它在spring-security bean上發送錯誤。我不認爲由於依賴於這些豆類，我應該在哪裏吸菸？它在兩天前工作得很好，項目的配置沒有改變，現在我嘗試在虛擬機上籤出軟件包。編輯2： 它在VM上都不起作用。我無法理解爲什麼會出現這樣的問題。我也嘗試刪除該項目並重新檢查它，但它仍然無法工作，同樣的問題。 如果你們中的任何一個人都可以建議我如何看待它會很棒，我的團隊中沒有任何其他人遇到這個問題。
您是否使用eclipse的熱部署？ – Setu
@Setu不，我沒有使用它。我只使用maven插件，svn插件和tomcat 8.0 –
