记录一下以后好查 spring 设置注入 构造器注入

JumpFunction jumpFunction; //设置注入public void setJumpFunction(JumpFunction jumpFunction) {    this.jumpFunction = jumpFunction;}

JumpFunction jumpFunction;// 构造器注入public CatImp(JumpFunction jumpFunction) {    this.jumpFunction = jumpFunction;}

<bean id="cat" class="com.kuma.Test2.CatImp"><!-- 设置注入 --><!--  <property name="jumpFunction" ref="jumpFunction"></property>--><!-- 构造器注入 --><constructor-arg name="jumpFunction" ref="jumpFunction"></constructor-arg></bean><bean id="jumpFunction" class="com.kuma.Test2.JumpFunction"></bean>
