一.使用word文档编辑好模版，如下图：
编辑好模板之后选择另存为，保存为xml格式。
二.编写java代码
采用的是FreeMarker模板引擎。需要下载对应的jar包，如果用的是Maven，只需在pom.xml中加入以下代码即可。
<!-- 模版引擎用到的jar包 --> <dependency> <groupId>org.freemarker</groupId> <artifactId>freemarker</artifactId> <version>2.3.25-incubating</version> </dependency>
Service:
package Solin.service; import java.io.File; import java.io.FileOutputStream; import java.io.IOException; import java.io.OutputStreamWriter; import java.io.Writer; import java.net.URL; import java.util.Date; import java.util.HashMap; import java.util.List; import java.util.Locale; import java.util.Map; import org.springframework.beans.factory.annotation.Autowired; import org.springframework.stereotype.Service; import Solin.domain.Student; import Solin.mapper.DynamicallyGeneratedWordMapper; import freemarker.cache.URLTemplateLoader; import freemarker.core.ParseException; import freemarker.template.Configuration; import freemarker.template.MalformedTemplateNameException; import freemarker.template.Template; import freemarker.template.TemplateException; import freemarker.template.TemplateNotFoundException; @Service public class DynamicallyGeneratedWordService { private static Configuration freemarkerConfig; static { freemarkerConfig = new Configuration(Configuration.VERSION_2_3_22); freemarkerConfig.setEncoding(Locale.getDefault(), "UTF-8"); } @Autowired private DynamicallyGeneratedWordMapper dynamicallyGeneratedWordMapper; /** * 生成word文档 * @param filePath * @throws TemplateNotFoundException * @throws MalformedTemplateNameException * @throws ParseException * @throws IOException * @throws TemplateException */ public void genWordFile(String filePath) throws TemplateNotFoundException, MalformedTemplateNameException, ParseException, IOException, TemplateException{ List<Student> stuList = dynamicallyGeneratedWordMapper.getStudentList(); Map<String,Object> result = new HashMap<String,Object>(); result.put("date", new Date()); result.put("teacher", "Solin"); result.put("topic", "基于Java模板技术动态生成Word文档"); result.put("count", stuList.size()); result.put("maleCount", dynamicallyGeneratedWordMapper.getManNumber()); result.put("femaleCount", dynamicallyGeneratedWordMapper.getFemaleNumber()); result.put("stuList", stuList); freemarkerConfig.setTemplateLoader(new URLTemplateLoader() { @Override protected URL getURL(String arg0) { return DynamicallyGeneratedWordService.class.getResource("/test.xml");//此处需要注意test.xml模板的路径,不要搞错了，否则获取不到模板，我是放在src/main/java目录下 } }); Template temp = freemarkerConfig.getTemplate("test.xml"); File targetFile = new File(filePath); Writer out = new OutputStreamWriter(new FileOutputStream(targetFile),"UTF-8"); //执行模板替换 temp.process(result, out); out.flush(); } }我的test.xml文件的位置：
Student实体类：
package Solin.domain; /** * @author Solin * 学生信息实体类 * */ public class Student { private Integer id;//主键 private String name;//姓名 private String sex;//性别 private String age;//年龄 public Integer getId() { return id; } public void setId(Integer id) { this.id = id; } public String getName() { return name; } public void setName(String name) { this.name = name; } public String getSex() { return sex; } public void setSex(String sex) { this.sex = sex; } public String getAge() { return age; } public void setAge(String age) { this.age = age; } } Controller: package Solin.controller; import java.io.IOException; import java.util.List; import org.springframework.beans.factory.annotation.Autowired; import org.springframework.stereotype.Controller; import org.springframework.web.bind.annotation.RequestMapping; import org.springframework.web.bind.annotation.ResponseBody; import Solin.domain.Student; import Solin.service.DynamicallyGeneratedWordService; import freemarker.core.ParseException; import freemarker.template.MalformedTemplateNameException; import freemarker.template.TemplateException; import freemarker.template.TemplateNotFoundException; /** * @author Solin * 基于Java模板技术动态生成Word文档 */ @Controller public class DynamicallyGeneratedWordController { @Autowired private DynamicallyGeneratedWordService dynamicallyGeneratedWordService; @ResponseBody @RequestMapping("/getStudentList") public String getStudentList(){ String result = "成功"; try { dynamicallyGeneratedWordService.genWordFile("d://stu.doc"); } catch (TemplateNotFoundException e) { result = "失败"; e.printStackTrace(); } catch (MalformedTemplateNameException e) { result = "失败"; e.printStackTrace(); } catch (ParseException e) { result = "失败"; e.printStackTrace(); } catch (IOException e) { result = "失败"; e.printStackTrace(); } catch (TemplateException e) { result = "失败"; e.printStackTrace(); } return result; } } XML模版中需要做以下修改：
表格数据是多行的，所以要循环。
我们在xml模版中做以下修改：找到上图中红色框框所在的地方，然后按下图修改
里面的内容依次改为对应的：${stu.id} ${stu.name} ${stu.sex} ${stu.age}这里的id name sex age是和Student实体类对应的。
三.到此基本完成了动态模版的生成，测试结果图下图：
