private MyObject myObject = MyObjectFactory.getService();@H_502_8@在我的Foo.java类中
@Autowired private MyObject myObject;@H_502_8@在spring xml中,我有：
<bean id="MyObject" class="path.to.MyObjectFactory" factory-method="getService"></bean> <bean id="Foo" class="path.to.Foo"> <property name="myObject" ref="MyObject"/> </bean>@H_502_8@错误是
No matching bean of type [path.to.MyObject] found for dependency: expected at least 1 bean which qualifies as autowire candidate for this dependency.@H_502_8@
最佳答案
您尝试将MyObjectFactory类型的对象注入到path.to.Foo中,在其中应该有MyObject类型的对象.请按以下方式更改您的代码：
Foo：
public class Foo { private MyObject myObject; public void setMyObject(MyObject value) { myObject=value;} }@H_502_8@MyObjectFactory：
public class MyObjectFactory { public MyObject getService() { return new MyObject(); } }@H_502_8@春季xml：
<bean class="MyObjectFactory" id="factory" /> <bean id="myObject" factory-bean="factory" factory-method="getService" scope="prototype" /> <bean id="Foo" class="path.to.Foo"> <property name="myObject" ref="MyObject"/> </bean>@H_502_8@顺便说一下,@ Autowired和< property ...>在您的情况下表达相同的内容,因此您可以忽略其中一个.
更新：
我以为您不想要单例,这就是为什么我添加了scope =“ prototype”.如果您的MyObject实例假定为单例,请将其删除.
