今天在使用SpringContextHolder来获取一个bean的时候出现错误,报错如下:
java.lang.IllegalStateException: applicaitonContext属性未注入, 请在applicationContext.xml中定义SpringContextHolder.
at org.apache.commons.lang3.Validate.validState(Validate.java:826)
at com.jituan.common.util.SpringContextHolder.assertContextInjected(SpringContextHolder.java:79)

at com.jituan.batch.msghandler.MessageHandler$SmsTread.run(MessageHandler.java:185)
解决方案:
在spring-mvc.xml中加入配置后解决:
<!-- 全局变量以便可以获得对应的注入bean -->
<bean id="springContextHolder" class="com.jituan.common.util.SpringContextHolder" />
在SpringContextHolder类上加入注解@Service、@Lazy(false)
SpringContextHolder 具体实现:
import java.util.Map;

import org.springframework.context.ApplicationContext;
import org.springframework.context.ApplicationContextAware;

/**
*
*以静态变量保存Spring ApplicationContext, 可在任何代码任何地方任何时候中取出ApplicaitonContext.
* @author Bucky
*/
@Service
@Lazy(false)
public class SpringContextHolder implements ApplicationContextAware{

private static ApplicationContext applicationContext;


//实现ApplicationContextAware接口的context注入函数, 将其存入静态变量.
public void setApplicationContext(ApplicationContext applicationContext) {
SpringContextHolder.applicationContext = applicationContext;
}


//取得存储在静态变量中的ApplicationContext.
public static ApplicationContext getApplicationContext() {
checkApplicationContext();
return applicationContext;
}

//从静态变量ApplicationContext中取得Bean, 自动转型为所赋值对象的类型.
@SuppressWarnings("unchecked")
public static <T> T getBean(String name) {
checkApplicationContext();
return (T) applicationContext.getBean(name);
}


//从静态变量ApplicationContext中取得Bean, 自动转型为所赋值对象的类型.
//如果有多个Bean符合Class, 取出第一个.
@SuppressWarnings("unchecked")
public static <T> T getBean(Class<T> clazz) {
checkApplicationContext();
@SuppressWarnings("rawtypes")
Map beanMaps = applicationContext.getBeansOfType(clazz);
if (beanMaps!=null && !beanMaps.isEmpty()) {
return (T) beanMaps.values().iterator().next();
} else{
return null;
}
}

private static void checkApplicationContext() {
if (applicationContext == null) {
throw new IllegalStateException("applicaitonContext未注入,请在applicationContext.xml中定义SpringContextHolder");
}
}
