第三步测试：
private ApplicationContext ac = new ClassPathXmlApplicationContext("application-context.xml");
//测试dao
@Test
public void testDao() {
RoleMapper roleMapper = (RoleMapper) ac.getBean("roleMapper");
Role role = roleMapper.selectByPrimaryKey(1);
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");
}
