我正在使用spring web-flow 2.0,我需要将一个变量从子流返回到父流,如:
<end-state id="end" >
<output name="mvViewBean" value="viewBean" />
</end-state>
并在我的父流程中使用它,如:
<subflow-state id="updateSubflowState" subflow="mv-update" >
<on-exit>
<evaluate expression="mvService.onblabla(mvViewBean)" />
</on-exit>
</subflow-state>
我是否需要定义变量定义或其他内容？
我试图使用Maven来构建我的Spring 3项目，该项目在Maven之前可以正常工作，但是却出现此错误：

at …Spring Web Flow Action-State控制器应该返回什么？看看下面我的流程我有一个动作状态,基于对控制器的调用我可以去4个差异路径..
我不知道我必须在控制器中做出哪些更改才能传回去哪里.
以下是我的流程:
<action-state id="checkStatus">
<evaluate expression="flowControllerActions.checkStatus(member)" />
<transition on="NoSSN" to="NoSSN"/>
<transition on="MemberExists" to="endStateMemberExists" />
<transition on="IsDeceased" to="endStateMemberDeceased" />
<transition on="OK" to="address" />
</action-state>
这是我在控制器中的方法.有人可以请告诉我该做些什么来使tranistions工作:
public String checkStatus(Member member) {
LOGGER.debug("[" + member.toString() + "]");
//
// HOW DO I RETURN??
//
}
在Spring 3.2项目中,我正在引导一个具有注入属性的服务bean.使用属性文件中的@Required @Value(...)注入该属性.我确信属性文件可以通过spring上下文很好地识别出来.
请查看以下服务等级:
@Service
public class SomeService {
private String aURIString;
@Required
@Value("${someUrl}")
public void setaURIString(String aURIString) {
this.aURIString = aURIString;
}
private URI oamURI;
public SomeService() throws Exception {
super();
try {
oamURI = new URI(aURIString);
} catch (URISyntaxException e) {
throw new Exception("URISyntaxException created while creating a URI instance for url= "+aURIString);
}
}
}
另请参阅下面的配置类
@Configuration
@EnableWebMvc
@PropertySource({ "classpath:filter.properties" })
@ComponentScan(basePackages = { "com.someOrg.SomePrj" })
public class WebConfig extends WebMvcConfigurerAdapter {
@Bean
public static PropertySourcesPlaceholderConfigurer properties() …我正在使用Spring Framework 4.1.5,Spring Security 4.0.0.RC2,Spring Webflow 2.4.0.RELEASE和Tomcat 8.0.15.

如何仅在一个转换上停止表单验证.使用以下代码我打开表单验证,一切都运行良好,但如果用户单击"取消"我不想运行表单验证.不管怎么说？
<view-state id="helloworld" view="input.jsp" model="customer" popup="true">
<transition on="submit" to="preview" />
<transition on="cancel" to="thanks"/>
</view-state>
