2、使用模板生成HTML代码

2.1 数据模型

public class User {

private String username;

private String password;

private Integer age;

private String address;

//省略setter和getter方法
}

2.2 FreeMarker模板

<!DOCTYPE html>
<html>
<head>
<meta charset="UTF-8">
<title>用户信息</title>

<link rel="stylesheet"
href="http://cdn.bootcss.com/bootstrap/3.3.0/css/bootstrap.min.css" />
</head>
<body style="font-family:'Courier New'">
<h3 class="text-center">这是用户${username}的信息页！</h3>
<div class="col-md-6 column">
<table class="table table-bordered">
<tr>
<th>用户名</th>
<th>密码</th>
<th>年龄</th>
<th>地址</th>
</tr>
<tr>
<td>${username}</td>
<td>${password}</td>
<td>${age}</td>
<td>${address}</td>
</tr>
</table>
</div>
</body>
</html>

2.3 使用FreeMarker生成HTML代码

/**
* 使用模板生成HTML代码
*/
public static void createHtmlFromModel() {
FileWriter out = null;
try {
// 通过FreeMarker的Confuguration读取相应的模板文件
Configuration configuration = new Configuration(Configuration.VERSION_2_3_23);
// 设置模板路径
configuration.setClassForTemplateLoading(CreateHtmlByFreemarker.class, "/static/ftl");
// 设置默认字体
configuration.setDefaultEncoding("utf-8");

// 获取模板
Template template = configuration.getTemplate("user.ftl");
//设置模型
User user = new User("tom", "hahahah", 28, "上海市");

//设置输出文件
File file = new File("e:/html/result.html");
if(!file.exists()) {
file.createNewFile();
}
//设置输出流
out = new FileWriter(file);
//模板输出静态文件
template.process(user, out);
} catch (TemplateNotFoundException e) {
e.printStackTrace();
} catch (MalformedTemplateNameException e) {
e.printStackTrace();
} catch (ParseException e) {
e.printStackTrace();
} catch (IOException e) {
e.printStackTrace();
} catch (TemplateException e) {
e.printStackTrace();
} finally {
if(null != out) {
try {
out.close();
} catch (IOException e) {
e.printStackTrace();
}
}
}
}

3、使用String作为FreeMarker模板，生成HTML代码

3.1 数据模型使用2.1模型

3.2 模板使用2.2模板

3.3 使用FreeMarker生成HTML代码

/**
* 把模板读入到String中，然后根据String构造FreeMarker模板
*/
public static void createHtmlFromString() {
BufferedInputStream in = null;
FileWriter out = null;
try {
//模板文件
File file = new File("D:/EclipseLearnSpace/ResearchSpace/Html2Pdf/src/main/resources/static/html/user.html");
//构造输入流
in = new BufferedInputStream(new FileInputStream(file));
int len;
byte[] bytes = new byte[1024];
//模板内容
StringBuilder content = new StringBuilder();
while((len = in.read(bytes)) != -1) {
content.append(new String(bytes, 0, len, "utf-8"));
}

//构造Configuration
Configuration configuration = new Configuration(Configuration.VERSION_2_3_23);
//构造StringTemplateLoader
StringTemplateLoader loader = new StringTemplateLoader();
//添加String模板
loader.putTemplate("test", content.toString());
//把StringTemplateLoader添加到Configuration中
configuration.setTemplateLoader(loader);

//构造Model
User user = new User("tom", "kkkkk", 29, "北京山东");
//获取模板
Template template = configuration.getTemplate("test");
//构造输出路
out = new FileWriter("e:/html/result.html");
//生成HTML
template.process(user, out);
} catch (FileNotFoundException e) {
e.printStackTrace();
} catch (UnsupportedEncodingException e) {
e.printStackTrace();
} catch (IOException e) {
e.printStackTrace();
} catch (TemplateException e) {
e.printStackTrace();
} finally {
if(null != in) {
try {
in.close();
} catch (IOException e) {
e.printStackTrace();
}
}
if(null != out) {
try {
out.close();
} catch (IOException e) {
e.printStackTrace();
}
}
}

}

4、使用String模板，模板中使用List

4.1 数据模型

public class Classes {

private String classId; // 班级ID

private String className; // 班级名称

private List<User> users;

public String getClassId() {
return classId;
}

//省略settter和getter方法

}

4.2 FreeMarker模板

<!DOCTYPE html>
<html>
<head>
<meta charset="UTF-8">
<title>班级信息</title>

<link rel="stylesheet"
href="http://cdn.bootcss.com/bootstrap/3.3.0/css/bootstrap.min.css" />
<style type="text/css">
.table-align{
margin-left: 25%;
}
</style>
</head>
<body style="font-family:'Courier New'">

<h3 class="text-center">下面是班级ID【${classId}】，班级名称【${className}】的人员信息</h3>
<div class="col-md-6 column table-align">
<table class="table">
<tr>
<th>姓名</th>
<th>密码</th>
<th>年龄</th>
<th>地址</th>
</tr>

<#list users as user>
<tr>
<td>${user.username}</td>
<td>${user.password}</td>
<td>${user.age}</td>
<td>${user.address}</td>
</tr>
</#list>
</table>
</div>
</body>
</html>

4.3 使用FreeMarker生成HTML代码

/**
* 根据String模板生成HTML，模板中存在List循环
*/
public static void createHtmlFromStringList() {
BufferedInputStream in = null;
FileWriter out = null;
try {
//模板文件
File file = new File("D:/EclipseLearnSpace/ResearchSpace/Html2Pdf/src/main/resources/static/html/class.html");
//构造输入流
in = new BufferedInputStream(new FileInputStream(file));
int len;
byte[] bytes = new byte[1024];
//模板内容
StringBuilder content = new StringBuilder();
while((len = in.read(bytes)) != -1) {
content.append(new String(bytes, 0, len, "utf-8"));
}

//构造Configuration
Configuration configuration = new Configuration(Configuration.VERSION_2_3_23);
//构造StringTemplateLoader
StringTemplateLoader loader = new StringTemplateLoader();
//添加String模板
loader.putTemplate("test", content.toString());
//把StringTemplateLoader添加到Configuration中
configuration.setTemplateLoader(loader);

//构造Model
Classes classes = new Classes();
classes.setClassId("23");
classes.setClassName("实验一班");
List<User> users = new ArrayList<User>();
User user = new User("tom", "kkkkk", 29, "北京");
users.add(user);
User user2 = new User("Jim", "hhhh", 22, "上海");
users.add(user2);
User user3 = new User("Jerry", "aaaa", 25, "南京");
users.add(user3);
classes.setUsers(users);
//获取模板
Template template = configuration.getTemplate("test");
//构造输出路
out = new FileWriter("e:/html/result.html");
//生成HTML
template.process(classes, out);
} catch (FileNotFoundException e) {
e.printStackTrace();
} catch (UnsupportedEncodingException e) {
e.printStackTrace();
} catch (IOException e) {
e.printStackTrace();
} catch (TemplateException e) {
e.printStackTrace();
} finally {
if(null != in) {
try {
in.close();
} catch (IOException e) {
e.printStackTrace();
}
}
if(null != out) {
try {
out.close();
} catch (IOException e) {
e.printStackTrace();
}
}
}

}
