提交的数据不存储在数据库中

标签： spring hibernate spring-boot spring-data-jpa

在我目前的spring-boot项目中，我有一个用Thymeleaf构建的页面，我有一个这样的表单：

<form class="form" role="form" method="post" th:action="@{/__${command.getClass().getSimpleName()}__/cadastra}">
   ...
</form>

呈现给：

<form class="form" role="form" method="post" action="/Usuario/cadastra">
    ...
</form>

当我尝试提交表单时发生问题：触发以下错误：

error: "Internal Server Error"
exception: "org.thymeleaf.exceptions.TemplateInputException"
message: "Error resolving template "Usuario/cadastra", template might not exist or might not be accessible by any of the configured Template Resolvers"
path: "/Usuario/cadastra"
status: 500
timestamp: 1417225370311
在控制台中

，显示：

任何人都可以看到这里的问题是什么？

PS：提交数据的处理程序是这种控制器方法：

  @RequestMapping(value = "cadastra", method=RequestMethod.POST)
  public void cadastra(@ModelAttribute("object") E object, BindingResult result) {
    serv.cadastra(object);
  }

更新

我解决了将注释@ResponseBody添加到控制器中的方法上面的错误，但现在我还有另一个问题：尽管没有显示更多错误，但提交的数据不会保存在数据库中（如果我尝试也会出现同样的情况）更新或删除对象）。

处理此操作的控制器中的方法是：

  @RequestMapping(value = "cadastra", method=RequestMethod.POST)
  @ResponseBody
  public void cadastra(@ModelAttribute("object") E object, BindingResult result) {
    serv.cadastra(object);
  }

  @RequestMapping(value = "altera", method=RequestMethod.POST)
  @ResponseBody
  public void altera(@ModelAttribute("object") E object, BindingResult result) {
    serv.altera(object);
  }

  @RequestMapping(value = "remove", method=RequestMethod.POST)
  @ResponseBody
  public void remove(@ModelAttribute("object") E object, BindingResult result) {
    serv.remove(object);
  }

在我的服务类中：

  @PreAuthorize("hasPermission(#user, 'cadastra_'+#this.this.name)")
  @Transactional
  public void cadastra(E object) {
    dao.insert(object);
  }

  @PreAuthorize("hasPermission(#user, 'altera_'+#this.this.name)")
  @Transactional
  public void altera(E object) {
    dao.update(object);
  }

  @PreAuthorize("hasPermission(#user, 'remove_'+#this.this.name)")
  @Transactional
  public void remove(E object) {
    dao.delete(object);
  }

在我的Dao课程中：

@Transactional
public void insert(E object) {
    getEntityManager().persist(object);
}

@Transactional
public void update(E object) {
    getEntityManager().merge(object);
}

@Transactional
public void delete(E object) {
    getEntityManager().remove(object);
}

现在有什么不对？

问题是模板丢失了。如果您的模板位于与默认位置不同的位置，则需要从@RequestMapping返回字符串。

我设法使用这个结构修复了这个pooblem到我的dao类的方法：

public void insert(E object) {
    EntityManager entityManager = getEntityManager();
    entityManager.getTransaction().begin();
        entityManager.persist(object);
    entityManager.getTransaction().commit();
}
