如何從jar將Java項目導入eclipse？
[英]How to import Java project into eclipse from jar?
問題描述
因此，已經給了我這樣結構的客戶端代碼。 client-context.xml是spring bean配置。
client
|
+-- config
| |
| +--client.properties
| +--client-context.xml
| +--keystore.jks
| +--request.xml
|
+-- lib
| |
| +--client.jar
| +--app-model.jar
| +--spring-aop.jar
| +--spring-beans.jar
| +--spring-context.jar
| -- other dependencies--
+--run.bat
我解壓縮了client.jar，因為我需要對其進行修改。
它的結構是這樣的
client-1.0
|
+--package
| |
| +--client.class
| +--client.java
| +--clientImpl.class
| +--clientImpl.java
|
+--META-INF
| |
| +--MANIFEST.MF
我試圖用以下結構在eclipse中創建一個項目。 我還把其他罐子作為依賴項
client
|
+--src
| |
| +--package
| | |
| | +--client.java
| | +--clientImpl.java
| |
| +--main
| | |
| | +--resources
| | | |
| | | +--client-context.xml
| | | +--client.properties
| | | +--keystore.jks
| | | +--request.xml
| |
| +--META-INF
| | |
| | +--MANIFEST.MF
我有一個例外
線程“主”中的異常org.springframework.beans.factory.NoSuchBeanDefinitionException：類型為[package.Client]的合格bean沒有在org.springframework.beans.factory.support.DefaultListableBeanFactory.getBean（DefaultListableBeanFactory.java:319）上定義org.springframework.context.support.AbstractApplicationContext.getBean（AbstractApplicationContext.java:985）在package.ClientImpl.main（ClientImpl.java:164）
這是我所處環境的相關標准
<bean class="org.springframework.beans.factory.config.PropertyPlaceholderConfigurer">
<property name="location" value="classpath:client.properties" />
</bean>
<util:properties id="ePSProperties" location="classpath:client.properties" />
<bean id="epsClient" class="package.ClientImpl" />
以及代碼的相關部分，則在ctx.getBean處引發了異常
public static void main(String[] args) {
ClassPathXmlApplicationContext ctx = new ClassPathXmlApplicationContext(
"classpath*:client-context.xml");
Client epsClient = ctx.getBean(Client.class);
epsClient.sendReceiveXmls();
epsClient.sendReceiveJavaObjects();
ctx.close();
}
更新：我想通了，我將context.xml移到src的根目錄。 我不確定最佳做法是什么。
編輯：我試圖將此項目用作動態Web項目（Maven項目）中的庫。 我的client-1.0項目安裝在本地存儲庫中。 以下是我的客戶代碼。
public class ClientImpl implements Client {
private static final String WS_ADDRESSING_ACTION = "http://www.example.org";

我通過創建客戶端實例來調用此庫。
ClientImpl clientImpl = new ClientImpl();
但是當我在以下位置調用sendReceiveObject時，出現了空指針異常
EnquiryResponse response = (EnquiryResponse) webServiceTemplate.marshalSendAndReceive(epvsEndpoint, request,
getCallback());
webServiceTemplate為null。 同樣，clientImpl中的所有字段均為空。 因此，自動接線是錯誤的。 應該怎么做？
1 個解決方案

該問題是由無法訪問的client-context.xml引起的。
指示Spring在類路徑中搜索此文件，但該文件所在的目錄尚未包含在類路徑中。
通過將文件移到根目錄（屬於類路徑），我能夠解決該問題。
編輯：對於我的第二個問題，我跟隨這個家伙設計了帶有Spring建議的Java庫，並創建了一個SpringLoader類，該類加載了上下文並且可以正常工作。
