Question

我正在尝试将Spring与struts集成为我的控制器。 Spring会根据applicationContext.xml中的配置初始化bean，但是当我将bean id作为struts.xml中的action类引用时，它无法检测到。这是我的 struts.xml

 <?xml version="1.0" encoding="UTF-8" ?>
    <!DOCTYPE struts PUBLIC
    "-//Apache Software Foundation//DTD Struts Configuration 2.3//EN"
    "http://struts.apache.org/dtds/struts-2.3.dtd">

    <struts>

        <package name="default" extends="struts-default">

            <action name="getHome" class="baseAction" method="getToHome">
                <result name="success">/jsp/bcHome.jsp</result>
            </action>


        </package>

    </struts>

这是我的 applicationContext.xml

<?xml version="1.0" encoding="UTF-8"?>
    <beans xmlns="http://www.springframework.org/schema/beans"
    xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
    xsi:schemaLocation="http://www.springframework.org/schema/beans
    http://www.springframework.org/schema/beans/spring-beans-2.5.xsd">

        <bean id="baseAction" class="com.localityindia.bc.action.BaseAction">
            <property name="baseService" ref="baseService" />           
        </bean>

        <bean id="baseService" class="com.localityindia.bc.service.BaseServiceImpl">
            <property name="baseDao" ref="baseDao"/>
        </bean>

        <bean id="baseDao" class="com.localityindia.bc.dao.BaseDaoImpl" />

    </beans>

这是我的动作类

import com.localityindia.bc.service.BaseService;
import com.opensymphony.xwork2.ActionSupport;

public class BaseAction extends ActionSupport {

private BaseService baseService;

public String getToHome(){
    System.out.println("baseService : "+baseService);
    System.out.println("Inside Action... getting home page for you.");
//  baseService.getHomeDetails();
    return SUCCESS;
}

public void setBaseService(BaseService baseService) {
    System.out.println("Setting srevice : "+baseService);
    this.baseService = baseService;
}

}

这是我的输出：

Setting srevice : com.localityindia.bc.service.BaseServiceImpl@1bf72d9

请建议我该怎么做才能让bean id引用与struts.xml中的动作映射一起使用

Answer 1

你必须在类路径中拥有Struts 2 Spring插件，因此Spring会实例化Struts 2动作。

Struts无法使用spring生成的bean id引用action bean来进行依赖注入
