【问题描述】：
我正在尝试为我的项目与 activiti-engine 集成。我的父母 pom 使用 spring 3.1.1
这是我的 pom.xml 中的 activiti 配置：
<dependency>
<groupId>org.activiti</groupId>
<artifactId>activiti-engine</artifactId>
<version>5.16.3</version>
<exclusions>
<exclusion>
<artifactId>spring-beans</artifactId>
<groupId>org.springframework</groupId>
</exclusion>
</exclusions>
</dependency>

</exclusion>
</exclusions>
</dependency>
<dependency>
<groupId>com.h2database</groupId>
<artifactId>h2</artifactId>
<version>1.2.132</version>
</dependency>
这也是我的 beans.xml
<bean id="dataSource" class="org.springframework.jdbc.datasource.SimpleDriverDataSource">
<property name="driverClass" value="org.h2.Driver" />
<property name="url" value="jdbc:h2:mem:activiti;DB_CLOSE_DELAY=1000" />
<property name="username" value="sa" />
<property name="password" value="" />
</bean>
<bean id="transactionManager" class="org.springframework.jdbc.datasource.DataSourceTransactionManager">

<property name="dataSource" ref="dataSource" />
<property name="transactionManager" ref="transactionManager" />

<bean id="historyService" factory-bean="processEngine" factory-method="getHistoryService" />
<bean id="managementService" factory-bean="processEngine" factory-method="getManagementService" />
<!-- Implementation class for pricingserv-->
<bean id="pricingServBean" class="com.paypal.pricing.service.core.PricingServImpl">
<property name="runtimeService" ref="runtimeService"/>
</bean>
以下是我尝试访问 runtimeService 的地方
public class PricingServImpl implements PricingServ {
private static Logger mLogger = Logger.getInstance(PricingServImpl.class);
private RuntimeService runtimeService;
public void setRuntimeService(RuntimeService runtimeService) {
this.runtimeService = runtimeService;
}
但我遇到了以下
Caused by: org.springframework.beans.ConversionNotSupportedException: Failed to convert property value of type 'org.activiti.engine.impl.RuntimeServiceImpl' to required type 'org.activiti.engine.RuntimeService' for property 'runtimeService'; nested exception is java.lang.IllegalStateException: Cannot convert value of type [org.activiti.engine.impl.RuntimeServiceImpl] to required type [org.activiti.engine.RuntimeService] for property 'runtimeService': no matching editors or conversion strategy found

有没有人遇到过类似的问题。
【问题讨论】：
-
您对这个异常的最初想法是什么？哪一行导致异常？
-
看起来注入 bean 会导致问题。我看到 getRuntimeService 正在返回 RuntimeServiceImpl 的对象。虽然理论上它不应该产生问题，因为 RuntimeServiceImpl 实现了 RuntimeService
-
我不知道这是否有任何用处，但它似乎类似于stackoverflow.com/q/25205324 - 也许你可以从那里的答案中得到一些线索。
-
我试过 stackoverflow.com/q/25205324 但它不起作用，因为 Activiti 不允许自动装配字段，另一种解决方法是使用 aop:config 给出上述确切错误
