Spring boot Spring引导自动生成控制器

在官方的Spring教程代码中，没有需要的控制器，因此我没有将它们放在示例中，但是当我尝试运行我的简单应用程序时，我一直在为错误寻找答案：

白标错误页面

此应用程序没有/error的显式映射，因此您可以看到 这是一种退路。2017年3月9日星期四10:18:51 CET有一个 意外错误（类型=未找到，状态=404）。没有可用的消息

结构：

    protected Invoice() {

    public Invoice(String issuedBy) {
        this.issuedBy = issuedBy;
    }
}

回购：

1。有什么问题吗？

2。这是否是导致问题的lombok（尽管使用start.spring.io初始值设定项）？

您忘了用

@RepositoryRestResource

注释存储库。如果不这样做，Spring将不会自动生成url映射，它将只是作为一个普通的存储库。这是spring数据rest的一个特性。因此，在你的情况下：

@RepositoryRestResource(collectionResourceRel = "invoices", path = "invoices")
public interface InvoiceRepository extends PagingAndSortingRepository<Invoice, Long> {
    List<Invoice> findByIssuedBy(@Param("issuer")String issuer);
}

@RepositoryRestResource（collectionResourceRel=“invoices”，path=“invoices”）
公共接口InvoiceRepository扩展了分页和排序存储库{
列表findByIssuedBy（@Param（“发卡机构”）字符串发卡机构）；
}

现在

curlhttp://localhost:8080/invoices

将返回所有发票

有关更多信息，请参阅。

谢谢您的回复。不过，我检查了教程：它指出导出存储库不需要“@RepositoryRestResource”。它仅用于更改导出详细信息，例如使用/people而不是默认值/people。您可以参考此信息吗，因为我发现他们的提示有点误导性？即使在复制粘贴代码并检查链接之后
