SSH框架单元测试工具类

 

package test.tools;
/**
 * @(#)TTool.java 2012-02-08 初版
 * Spring框架单元测试辅助工具类
 * 
 * 单元测试使用必看:
 *   TTool类说明
 *     - TTool.getBean(String beanName);
 *       根据Spring配置文件中的bean的id获取实体对象
 *     - TTool.testBegin();
 *     - TTool.testEnd();
 *	 测试开始调用TTool.testBegin(),测试结束调用TTool.testEnd(),模拟OpenSessionInViewFilter功能
 ***************直接输出****************
 *     - TTool.print(Map gridMap)
 *       将分页方法取得的实体列表中的实体装换为JSON字符串,并输出
 *     - TTool.print(Object object)
 *   	   将对象实体转换为json字符串,并输出.
 *     - TTool.print(List list)
 *       将列表对象装换为json字符串,并输出
 ***************格式化输出*****************
 *     - TTool.println(Map gridMap)
 *       将分页方法取得的实体列表中的实体装换为JSON字符串,并输出
 *     - TTool.println(Object object)
 *   	   将对象实体转换为json字符串,并输出.
 *     - TTool.println(List list)
 *       将列表对象装换为json字符串,并输出
