Params that I send to getForEntityis correct, because when I send the same params but with correct dates - it's works good.
我发送到的参数getForEntity是正确的，因为当我发送相同的参数但日期正确时 - 效果很好。

You should use TestRestTemplateinstead of RestTemplate.
您应该使用TestRestTemplate而不是RestTemplate.
Class TestRestTemplate
类 TestRestTemplate
Convenient alternative of RestTemplate that is suitable for integration tests. They are fault tolerant, and optionally can carry Basic authentication headers. If Apache Http Client 4.3.2 or better is available (recommended) it will be used as the client, and by default configured to ignore cookies and redirects.
适用于集成测试的 RestTemplate 的方便替代品。它们是容错的，并且可以选择携带基本身份验证标头。如果 Apache Http Client 4.3.2 或更高版本可用（推荐），它将用作客户端，并且默认配置为忽略 cookie 和重定向。
