Spring java config EJB代理不工作
在使用Spring的java配置类时,让EJB bean工作起来有问题。 具体来说,我有以下几点可以发挥作用:
@Configuration
@ComponentScan(basePackages = "com.company.web.config")
@ImportResource(value = {"classpath:spring-beans.xml"})
public class AppConfig {
}
@Configuration
@ComponentScan(basePackages = "com.company.web")
public class WebConfig extends WebMvcConfigurationSupport {
// basic Spring MVC setup omitted
}
我的春豆。xml如下所示:
<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xmlns:jee="http://www.springframework.org/schema/jee"
xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans.xsd
http://www.springframework.org/schema/jee http://www.springframework.org/schema/jee/spring-jee.xsd">
<jee:local-slsb id="fooService" jndi-name="java:app/model/FooServiceBean!com.company.ejb.FooService"
business-interface="com.company.ejb.FooService" />
</beans>
通过这种配置,一切正常,我可以做到:
@Controller
public class HomeController {
private final FooService fooService;
@Autowired
public MyPageController(FooService fooService){
this.fooService = fooService;
}
// request methods
}
现在我试着去掉XML文件。根据the documentation的说法,本地slsb应该是等效的
<bean id="fooService"
class="org.springframework.ejb.access.LocalStatelessSessionProxyFactoryBean">
<property name="jndiName" value="java:app/model/FooServiceBean!com.company.ejb.FooService"/>
<property name="businessInterface" value="com.company.ejb.FooService"/>
</bean>
但是,如果我从AppConfig
中删除@ImportResource
并将此@Bean
方法改为@Bean
方法,则部署失败,因为无法实例化控制器(找不到FooService
的autowire候选者):
@Bean
public LocalStatelessSessionProxyFactoryBean fooService(){
LocalStatelessSessionProxyFactoryBean factory = new LocalStatelessSessionProxyFactoryBean();
factory.setBusinessInterface(FooService.class);
factory.setJndiName("java:app/model/FooServiceBean!com.company.ejb.FooService");
return factory;
}
你知道为什么这样不行吗?我使用的是Spring版本4.0.2
# 1 楼答案
问题似乎与读取配置的顺序有关,可能与双重配置加载有关
具体来说,引入一个单独的配置类并在WebConfig之前导入它似乎可以做到这一点,比如:
