Spring Boot之thymeleaf中替换th:each使用

创建实体类：Produce.java:

package priv.doublechen.Springbootproject.entity;

public class Product {
	private String name;
	private double price;
	private int inStock;
	public String getName() {
		return name;
	}
	public void setName(String name) {
		this.name = name;
	}
	public double getPrice() {
		return price;
	}
	public void setPrice(double price) {
		this.price = price;
	}
	public int getInStock() {
		return inStock;
	}
	public void setInStock(int inStock) {
		this.inStock = inStock;
	}
	public Product(String name, double price, int inStock) {
		super();
		this.name = name;
		this.price = price;
		this.inStock = inStock;
	}
	
}

　　在控制器中加入：

@RequestMapping("welcome")
	public String welcome(Map<String,Object> map){
		map.put("abc", "123");//给request域中放入welcome
		//给thymeleaf 准备数据
		List<Product> prods = new ArrayList<>();
		prods.add(new Product("a",100,10));
		prods.add(new Product("b",200,20));
		prods.add(new Product("c",300,30));
		map.put("prods", prods);
		return "result";
	}

　　在result.html中加入：

<!DOCTYPE html>
<html xmlns:th="http://www.thymeleaf.org">
<head>
<meta charset="UTF-8">
<title>Insert title here</title>
</head>
<body>
	<p th:text="${abc}">Welcome to thymeleaf...!</p>
	<p>Welcome to thymeleaf...!</p>
	<h1>Product list</h1>
	<table>
		<tr>
			<th>NAME</th>
			<th>PRICE</th>
			<th>IN STOCK</th>
		</tr>
		<tr th:each="prod : ${prods}">
			<td th:text="${prod.name}">Onions</td>
			<td th:text="${prod.price}">2.41</td>
			<td th:text="${prod.inStock}">yes</td>
		</tr>
	</table>
</body>
</html>

　　运行结果：

因为每次springboot项目中的html文件代码发生修改，总是得重新运行主类，特别麻烦，所以在pom.xml文件中添加依赖：

<!-- 加入以下依赖，代码做了修改，不用重新运行 -->
        <dependency>
            <groupId>org.springframework</groupId>
            <artifactId>springloaded</artifactId>
            <version>1.2.8.RELEASE</version>
        </dependency>
        <dependency>
            <groupId>org.springframework.boot</groupId>
            <artifactId>spring-boot-devtools</artifactId>
        </dependency>

　　maven ->update project

每次修改代码自动编译，只要刷新页面就OK了。
