Does the parameter type of the setter match the return type of the getter?

配置spring时，遇到了一个小问题。提示can't create inner bean .......  Does the parameter type of the setter match the return type of the getter?    在网上收了下，找到了解决方法。自己记录下。

 

spring配置文件要求在server设置getter和setter，而且方法名有要求，bean id 首字母小写

如spring配置为：

<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE beans PUBLIC "-//SPRING//DTD BEAN//EN" "http://www.springframework.org/dtd/spring-beans.dtd">
<beans>
<!--定义业务逻辑服务类-->
<bean id="saleinfoService" parent="hibernateTransactionProxy">
    <property name="target">
      <bean class="com.mfsoft.platform.saleinfo.service.SaleinfoServiceImpl">
        <property name="saleinfoDAO">
          <ref local="saleinfoDAO"/>
        </property>
      </bean>
    </property>
</bean>

<!--定义DAO-->
<bean id="saleinfoDAO" class="com.mfsoft.platform.saleinfo.dao.SaleinfoDAOImpl">
    <property name="hibernateTemplate">
      <ref bean="hibernateTemplate" />
    </property>
</bean>
</beans>

则SaleinfoServiceImpl应写为：

public class SaleinfoServiceImpl extends BaseServiceImpl<SaleBasic,Integer> implements SaleinfoService {
private SaleinfoDAO testDAO;

public SaleinfoDAO getSaleinfoDAO() {
   return testDAO;
}

public void setSaleinfoDAO(SaleinfoDAO testDAO) {
   this.testDAO = testDAO;
}

}
