eclipse编写spring等xml配置文件时只有<bean>、<context>等有提示，其他标签都没有提示
这时就需要做以下两步操作（下面以事务管理标签为例）
1，添加命名空间“xmlns:tx”
xmlns:tx="http://www.springframework.org/schema/tx"
2，在“xsi:schemaLocation”里新增xsd文件路径
http://www.springframework.org/schema/tx http://www.springframework.org/schema/tx/spring-tx-3.2.xsd
下面是一个完整的示例
<?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:context="http://www.springframework.org/schema/context"
xmlns:tx="http://www.springframework.org/schema/tx"
xsi:schemaLocation="
http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context-3.2.xsd
http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans-3.2.xsd
http://www.springframework.org/schema/tx http://www.springframework.org/schema/tx/spring-tx-3.2.xsd">
