maven依赖

<dependency>
    <groupId>org.freemarker</groupId>
    <artifactId>freemarker</artifactId>
    <version>2.3.13</version>
</dependency>

代码：

package w0151023;

import freemarker.cache.StringTemplateLoader;
import freemarker.template.Configuration;
import freemarker.template.Template;
import freemarker.template.TemplateException;

import java.io.IOException;
import java.io.StringWriter;
import java.util.HashMap;
import java.util.Map;

    public static void main(String[] args) {
        Configuration cfg = new Configuration();
        StringTemplateLoader stringLoader = new StringTemplateLoader();
        String templateContent = "欢迎：${name}";
        stringLoader.putTemplate("myTemplate", templateContent);
        cfg.setTemplateLoader(stringLoader);

        try {
            Template template = cfg.getTemplate("myTemplate", "utf-8");
            Map root = new HashMap();
            root.put("name", "javaboy2012");

            StringWriter writer = new StringWriter();
            try {
                template.process(root, writer);
                System.out.println(writer.toString());
            } catch (TemplateException e) {
                e.printStackTrace();
            }
        } catch (IOException e) {
            e.printStackTrace();
        }
    }
}
