帮忙看看这个bean的属性赋值，为什么会这样。

Question

<!-- PeriodAction -->
<bean name="periodAction" class="com.shandy.scra.bas.web.PeriodAction" singleton="false">
<property name="periodService" ref="periodService"/>   //
<property name="operaService" ref="periodService"/> //这里不执行
<property name="testPrefix" value="ymf"/>
<property name="pageService" ref="pageService"></property>
</bean>我在PeriodaAction里的代码 public void setOperaService(PeriodService operaService) {
this.operaService = operaService;
this.periodService = operaService;
System.out.println("setOperaService");
} public void setPeriodService(PeriodService periodService) {
this.periodService = periodService;
System.out.println("setPeriodService");
}
public void setTestPrefix(String testPrefix) {
this.testPrefix = testPrefix;
System.out.println(this.testPrefix);
}
tomcat的输出:
22:31:35,546  WARN OgnlValueStack:46 - Could not find property [struts.valueStack]
setPeriodService  //看到没只有这里
Hibernate: select period0_.id as id29_, period0_.accPeriod as accPeriod29_, period0_.accountId as 
今天整了一天。哎。不知道怎么回事
哪位有经验的大哥碰到过这种问题吗？

Answer 1

public void setOperaService(PeriodService operaService) {
this.operaService = operaService;
this.periodService = operaService;
System.out.println("setOperaService");
}
把this.periodService = operaService;删掉呢

我怕代码太多，大家看的太烦了。
