第一步：添加jar包

第二步：配置文件

第三步测试：
 private ApplicationContext ac = new ClassPathXmlApplicationContext("application-context.xml");

	//测试dao
	@Test
	public void testDao() {

	    System.out.println(role.getDescription());
	    int num = roleMapper.insert(new Role("abc","哈哈"));
	    System.out.println(num);

	}
	//测试service和事务
	@Test
	public void testService() {
		RoleService roleService = (RoleService) ac.getBean("roleServiceImpl");
		roleService.save(new Role("abc","哈哈"));
	
//		List<Role> list = roleService.getByIds(new int [] {1,2,3,4,5});
//		for(Role role : list) {
//			System.out.println(role.getName() + "  " + role.getDescription());
//		}
	}
	
	//测试action
    @Test
	public void testAction() {
		RoleAction roleAction =  (RoleAction) ac.getBean("roleAction");
