问题描述

我的控制器函数成功返回数组。



我的控制器代码是:

  private JdbcTemplate jdbcTemplate; 

@Autowired
ConfigurationController configcon = new ConfigurationController(jdbcTemplate);

@RequestMapping(value =/)
public String index(Model model){
model.addAttribute(users,configcon.getQuery(customers)) ;
返回forward:/index.html;
}

但是如何在webapp中使用这个数组(例如用户) index.html?



我想在html表格中显示数据库值。



Please Advice。

解决方案

您需要一个模板引擎。 Spring支持:



来源: docs



这些语言允许您根据模型动态生成HTML页面。使用Thymeleaf,您可以使用 th:每个属性遍历模型,例如:

 <表> 
< thead>
< tr>
< th> ID< / th>
< th>名称< / th>
< / tr>
< / thead>
< tbody>
< tr th:each =customer:$ {customers}>
< td th:text =$ {customer.id}>& nbsp;< / td>
< td th:text =$ {customer.name}>& nbsp;< / td>
< / tr>
< / tbody>
< / table>

在本例中,我循环遍历模型 $ {customers} (因为您在控制器中将其命名),并为每个客户生成一行两列,一列用于ID,另一列用于名称。这些代表了客户类中的属性(带适当的getter / setter)。



每个模板引擎都提供了循环模型的不同方式,对于这个答案太多了。


My Controller function return array successfully.

My Controller Code is :

private JdbcTemplate jdbcTemplate;

@Autowired
ConfigurationController configcon = new ConfigurationController(jdbcTemplate);

@RequestMapping(value = "/")
public String index(Model model) {
    model.addAttribute("users", configcon.getQuery("customers"));
    return "forward:/index.html" ;
}

But How to use this array (For ex., users) in webapp/index.html?

I want to display the database values in html table.

Please Advice.

Thank you.

解决方案

You need a templating engine for that. Spring supports:

Source: docs

These languages allow you to dynamically generate a HTML page based on your model. With Thymeleaf you could use the th:each attribute to loop over your model, for example:

<table>
  <thead>
    <tr>
      <th>ID</th>
      <th>Name</th>
    </tr>
  </thead>
  <tbody>
    <tr th:each="customer : ${customers}">
      <td th:text="${customer.id}">&nbsp;</td>
      <td th:text="${customer.name}">&nbsp;</td>
    </tr>
  </tbody>
</table>

In this example I'm looping over the model ${customers} (because you named it like that in your controller), and for each customer a row is generated with two columns, one for the ID and another one for the name. These represent properties (with proper getter/setter) in your customer class.

Each of the templating engines provide a different way for looping over your model, showing them all would probably be too much for this answer.
