我正在尝试 gt 我创建的特定 java 类对象的方法列表并尝试对其进行单元测试。

它失败说它找不到具有“java.lang.ClassNotFoundException:class com.jr.freedom.user.User”的类

这是测试代码:

    @Test
    public void testRegisterNewUser() throws InvalidDataException {
        userService = new UserService();
        try {
            Class classUser = Class.forName(User.class.toString());
            Method m[] =classUser.getDeclaredMethods();
            for(int i = 0; i < m.length; i++){
                System.out.println(m[i].toString());
            }
        } catch (ClassNotFoundException e) {
            // TODO Auto-generated catch block
            e.printStackTrace();
            fail(e.getMessage());
        }


        assertNotNull(createTestUserJson());
}

我的项目包如下所示:

在项目文件夹内:src test

User 类在 src>com>jr?freedom>user 中(代表 com.jr.freedom.user.User),而测试类在 test>test>com>jr>freedom>user 中(代表 test.com.jr .freedom.user.UserServiceTest)

起初,/test 目录中的包名称与用户对象的 /src 目录中的包标签相同,但这并没有起作用,因为我认为 java relfection 试图检索 /test 文件夹中的用户对象,所以我重命名了包,使其独一无二,但仍然无法正常工作。有什么建议吗?谢谢

User.class 的结果。toString()是:

class com.jr.freedom.user.User

在真正的类名开始之前看到?这使字符串成为非法的类名。

您需要使用getName()

该类返回:toString所以它正在尝试加载:(如您的错误消息所述)Class"class com.foo.NameOfClass"class com.jr.freedom.user.User

但更重要的是,你已经有了类:User.class,为什么还要尝试加载呢?只需拿出那条线并拥有:

User.class.getDeclaredMethods...
