springboot下载doc⽂档
1、先个⼀个doc的⽂件，另存为⼀份xml格式的⽂件，把名字改成fit⽂件放到resources⽬录结构下⾯
2、修改pom⽂件，不然打包⽆法将resources⽬录下⾯的ftl⽂件打包进去
3、配置⼀个javaBean
import t.annotation.Bean;
import t.annotation.Configuration;
import org.springframework.web.servlet.view.freemarker.FreeMarkerConfigurer;
import java.util.HashMap;
import java.util.Map;
/**
* @Auther: lyl
* @Date: 2020/12/5 10:41
* @Description:
*/
@Configuration
public class ApplicationConfig {
@Bean(name = "freeMarkerConfigurer")
public FreeMarkerConfigurer freeMarkerConfigurer() {
FreeMarkerConfigurer configurer = new FreeMarkerConfigurer();
configurer.setDefaultEncoding("UTF-8");
configurer.setTemplateLoaderPath("classpath:/templates");
Map<String, Object> variables = new HashMap<>(1<<1);
variables.put("xml_escape","fmXmlEscape");
configurer.setFreemarkerVariables(variables);
return configurer;
}
}
4、注⼊这个bean，然后获取模板⽂件
@Autowired
private FreeMarkerConfigurer freeMarkerConfigurer;
public void findByIdSelectDownload(Long id, HttpServletResponse response) {
CaseDTO byIdSelect = this.findByIdSelect(id);
Map<String, Object> dataMap = new HashMap<>();
// 创建configuration对象，得到模板⽂件保存的⽬录
Configuration configuration = Configuration();
/
/ 加载⼀个模板⽂件，创建⼀个模板对象
Locale locale = new Locale("zh");
Template t=null;
try {
t = Template("case.ftl",locale,"UTF-8"); //获取模板⽂件
} catch (IOException e) {
e.printStackTrace();
}
Writer out = null;
springboot结构
try {
response.setContentType("multipart/form-data;charset=utf-8");
response.setHeader("Content-disposition", "attachment; filename=" + ("caseId")+".doc");
response.addHeader("Content-type", "application/octet-stream");
out = Writer();
t.process(dataMap, out); //将填充数据填⼊模板⽂件并输出到⽬标⽂件
} catch (TemplateException e) {
e.printStackTrace();
} catch (IOException e) {
e.printStackTrace();
} finally {
try {
if(out != null) {
out.close();
}
//                if(outFile != null) {
//                    outFile.delete();
//                }
} catch (IOException e) {
e.printStackTrace();
}
}
}
