[英]Adding data to two different tables from one form using spring and JPA
我正在尝试使用 JPA 和 Spring 将数据从一种形式添加到两个不同的表中。 通过将纬度和经度数据硬编码到其中一个表的服务类方法中，我能够弄清楚如何做到这一点； 但是，我不确定如何让用户自己输入纬度和经度的数据，这些数据位于同一表单的第二个表中。
addBreweries.jsp 表单代码是：
<form:form method="POST" action="/Assignment2/breweries/addBrewery" modelAttribute="brewerie">
<table>
<tr>
<td><form:label path="name">Name</form:label></td>
<td><form:input path="name" /></td>
<td style="color:red"><form:errors path="name"/> </td>
</tr>
<tr>
<td><form:label path="address1">Address 1</form:label></td>
<td><form:input path="address1" /></td>
<td style="color:red"><form:errors path="address1"/> </td>
</tr>
<tr>
<td><form:label path="address2">Address 2</form:label></td>
<td><form:input path="address2"/></td>
<td style="color:red"><form:errors path="address2"/> </td>
</tr>
<tr>
<td><form:label path="city">City</form:label></td>
<td><form:input path="city"/></td>
<td style="color:red"><form:errors path="city"/> </td>
</tr>
<tr>
<td><form:label path="state">State</form:label></td>
<td><form:input path="state"/></td>
<td style="color:red"><form:errors path="state"/> </td>
</tr>
<tr>
<td><form:label path="code">Code</form:label></td>
<td><form:input path="code"/></td>
<td style="color:red"><form:errors path="code"/> </td>
</tr>
<tr>
<td><form:label path="country">Country</form:label></td>
<td><form:input path="country"/></td>
<td style="color:red"> <form:errors path="country"/> </td>
</tr>
<tr>
<td><form:label path="phone">Phone Number</form:label></td>
<td><form:input path="phone"/></td>
<td style="color:red"> <form:errors path="phone"/> </td>
</tr>
<tr>
<td><form:label path="website">Website</form:label></td>
<td><form:input path="website"/></td>
<td style="color:red"><form:errors path="website"/> </td>
</tr>
<tr>
<td><form:label path="description">Description</form:label></td>
<td><form:input path="description"/></td>
<td style="color:red"> <form:errors path="description"/> </td>
</tr>
<tr>
<td><form:label path="addUser">Add User</form:label></td>
<td><form:input path="addUser"/></td>
<td style="color:red"> <form:errors path="addUser"/> </td>
</tr>
<tr>
<td><form:label path="creditLimit">Credit Limit</form:label></td>
<td><form:input path="creditLimit"/></td>
<td style="color:red"> <form:errors path="creditLimit"/> </td>
</tr>
<tr>
<td><form:label path="email">Email</form:label></td>
<td><form:input path="email"/></td>
<td style="color:red"> <form:errors path="email"/> </td>
</tr>
<tr>
<td><input type="submit" value="Submit"/></td>
</tr>
</table>
</body>
控制器的代码是：
@PostMapping("/addBrewery")
public ModelAndView addAnAgent(@ModelAttribute("brewerie") Breweries brewerie) {
Date date = new Date();
brewerie.setLastMod(date);
service.addAnBreweries(brewerie);
return new ModelAndView("redirect:/breweries");
}
我使用的服务类方法是：
public void addAnBreweries(Breweries brewerie) {
EntityManager em = DBUtil.getEMF().createEntityManager();
EntityTransaction trans = em.getTransaction();
Date date = new Date();
brewerie.setLastMod(date);
try {
trans.begin();
em.persist(brewerie);
trans.commit();
BreweriesGeocode bg = new BreweriesGeocode();
bg.setBreweryId((Integer) brewerie.getId());
bg.setLongitude(-97);
bg.setLatitude(30);
trans.begin();
em.persist(bg);
trans.commit();
} catch (Exception ex) {
System.out.println(ex);
} finally {
em.close();
}
}
