freemarker中还是有很多地方值得学习的地方

2019年11月15日

先上java 控制层的代码

@RequestMapping("/")
    public ModelAndView test(){
        ModelAndView modelAndView=new ModelAndView("/index");
        //单纯的赋值
        modelAndView.addObject("name","老铁");
        modelAndView.addObject("user","jimiy");

        //新建一个变量
        Product latestProduct=new Product();
        latestProduct.setUrl("unknowtime.top");
        latestProduct.setName("jimiy");
        latestProduct.setPrice(0);
        modelAndView.addObject("latestProduct",latestProduct);

        //list 1
        ArrayList<Animal> animals = new ArrayList<>();
        for (int i = 0; i <5 ; i++) {
            Animal animal = new Animal();
            animal.setName("jojo");
            animal.setPrice("100"+10*i);
            if(i%2==0)
                animal.setProtecte(true);
            else
                animal.setProtecte(false);
            animals.add(animal);
        }
        modelAndView.addObject("animals",animals);

        //list 2
        ArrayList<Animal> animalsnull = new ArrayList<>();
        modelAndView.addObject("animalsnull",animalsnull);

        //list 3
        ArrayList<String> fruits = new ArrayList<>();
        fruits.add("tomato");
        fruits.add("watermalon");
        fruits.add("Apple");
        fruits.add("Oragange");
        modelAndView.addObject("fruits",fruits);


        return modelAndView;
    }

再上试图层

<!DOCTYPE html>
<html lang="en">
<head>
    <meta charset="UTF-8">
    <title>Title</title>
    <style>
        .protecte {color:red}
        .oddRow {color:green}
        .evenRow {color:blue}
    </style>
</head>
<body>

<div>
    Hello,${name}
    <hr/>

    <h1>
        Welcome ${user}<#if user == "jimiy">, our beloved leader</#if>!
    </h1>
    <p>Our latest product: <a href="${latestProduct.url}">${latestProduct.name}</a>!</p>
    <hr/>

    <#if latestProduct.price == 0>
        <h3> Pythons are free today!</h3>
    </#if>
    <hr/>

    <p>We have these animals:
    <table border=1>
        <#list animals as animal>
        <tr><td>${animal.name}<td>${animal.price} Euros
                </#list>
    </table>
    <hr/>

    <#list animalsnull>
        <ul>
            <#items as animal>
            <li>${animal.price}
                </#items>
        </ul>
    </#list>
    <hr/>

    <p>Fruits: <#list animals as animal>${animal.price}<#sep>, </#list>
    <hr/>
    <p>Fruits: ${fruits?join(", ", "None")}
    <hr/>

    <#list animals>
    <p>Animal:</p>
    <ul>
        <#items as animal>
            <li>${animal.price}<#sep> and</#sep></li>
        </#items>
    </ul>
    <#else>
        <p>We have no animals.</p>
        </#list>
    <hr/>

    <#list animals as animal>
        <div<#if animal.protecte> class="protecte"</#if>>
            ${animal.name} for ${animal.price} Euros
        </div>
    </#list>
    <hr/>

    <#list animals as animal>
        <div<#if animal.protecte> class="protecte"</#if>>
            ${animal.name?upper_case} for ${animal.price} ===> ${animal.name?cap_first } for ${animal.price} ===> its length:${animal.name?length}
        </div>
    </#list>
    <h3>animals Size:${animals?size}</h3>
    <hr/>

    <table border=1>
        <#list animals as animal>
        <tr class="${animal?item_parity}Row"><td>${animal.name}<td>${animal.price} ===> ${animal?index}  <===> ${animal?counter} ==> ${animal.protecte?string('Y','N')}
                </#list>
    </table>
    <hr/>

    <h1>Welcome ${Visitor!"visitor"}!</h1>
    <#if Visitor??><h1>Welcome ${Visitor}!</h1> <#else><h1>Welcome,xxxxxx</h1></#if>
    <hr/>

    <#include "/copyright_footer.ftl">
</div>
</body>
</html>
