### 1.打开word模板,给需要赋值的位置先填上数据,方便查找编写freemarker代码,如下图 ###

### 2.将word文件另存为xml文件 到桌面 ,然后修改jhj.xml修改后缀 改为 jhj.ftl 文件 ###

###  3.测试数据 用json数据 ###

\{"jhj1":\[\{"name1":"H3C-S5024PV2-E1","name2":"政务内网核心交换机主1","name3":"1","name4":"备注1"\},\{"name1":"H3C-S5024PV2-E2","name2":"政务内网核心交换机主2","name3":"0","name4":"备注2"\},\{"name1":"H3C-S5024PV2-E3","name2":"政务内网核心交换机主3","name3":"0","name4":"备注3"\}\],"jhj2":\[\{"name1":"硬件/模块运行状况","name2":"1","name3":"硬件备注1","radio":1\},\{"name1":"运行环境-供电状况","name2":"0","name3":"环境备注2","radio":1\},\{"name1":"运行环境-机房温度","name2":"36℃","name3":"机房备注3","radio":2\},\{"name1":"运行环境-机房湿度","name2":"%","name3":"湿度备注4","radio":2\},\{"name1":"运行环境-通风状况","name2":"良好","name3":"通风备注5","radio":2\}\],"jhjform":\{"azaddress":"武汉市蔡甸区大数据中心","jctime":"2020-06-09","remarks":"建议经常查看情况"\}\}

4.测试代码+工具代码

public static void main(String[] args) {
            String jhj="{\"jhj1\":[{\"name1\":\"H3C-S5024PV2-E1\",\"name2\":\"政务内网核心交换机主1\",\"name3\":\"1\",\"name4\":\"备注1\"},{\"name1\":\"H3C-S5024PV2-E2\",\"name2\":\"政务内网核心交换机主2\",\"name3\":\"0\",\"name4\":\"备注2\"},{\"name1\":\"H3C-S5024PV2-E3\",\"name2\":\"政务内网核心交换机主3\",\"name3\":\"1\",\"name4\":\"备注3\"}],\"jhj2\":[{\"name1\":\"硬件/模块运行状况\",\"name2\":\"1\",\"name3\":\"硬件备注1\",\"radio\":1},{\"name1\":\"运行环境-供电状况\",\"name2\":\"0\",\"name3\":\"环境备注2\",\"radio\":1},{\"name1\":\"运行环境-机房温度\",\"name2\":\"36℃\",\"name3\":\"机房备注3\",\"radio\":2},{\"name1\":\"运行环境-机房湿度\",\"name2\":\"66%\",\"name3\":\"湿度备注4\",\"radio\":2},{\"name1\":\"运行环境-通风状况\",\"name2\":\"良好\",\"name3\":\"通风备注5\",\"radio\":2}],\"jhjform\":{\"azaddress\":\"政务中心\",\"jctime\":\"2020-06-09\",\"remarks\":\"建议经常查看情况\"}}";
            Map map = (Map) JSON.parse(jhj); //json转map
            Object jhj1 = map.get("jhj1"); //获取jhj1数据
            Object jhj2 = map.get("jhj2");  //获取jhjq2数据
            Object jhjform = map.get("jhjform"); //获取jhjform数据
            List<Map> jhj1List = (List)JSON.parseArray(jhj1.toString()); //转成list  map数据
            List<Map> jhj2List = (List)JSON.parseArray(jhj2.toString()); //转成list  map数据
            Map jhjform1 = (Map)JSON.parse(jhjform.toString());
            System.out.println("jhj2List======"+jhj2List);
            System.out.println();
            System.out.println("jhjform======="+jhjform1);
            for (int i=0; i<jhj1List.size();i++){  //为jhj1 数据添加序号值
                jhj1List.get(i).put("index",i+1);
            }
            System.out.println("jhj1List======"+jhj1List);
            System.out.println();
            Map<String,Object> map2=new HashMap<>(); //新建map
            map2.putAll(jhjform1);     //将jhjform放入map
            map2.put("jhj1List",jhj1List);  //将jhj1List也放入map
            map2.put("jhj2List",jhj2List);  //将jhj2List也放入map
            System.out.println();
            System.out.println(map2);
            try {
                ToWord.toWord(map2,"交换机"+".doc","jhj.ftl"); //生成word工具类
            }catch (Exception e){
                e.printStackTrace();
            }
        }
    }

public class ToWord {
    
        public static void toWord(Map<String, Object> dataMap, String docName, String ftlName) throws IOException {
            try {
                //Configuration用于读取ftl文件
                Configuration configuration = new Configuration();
                configuration.setDefaultEncoding("utf-8");
    
                /*以下是两种指定ftl文件所在目录路径的方式, 注意这两种方式都是
                 * 指定ftl文件所在目录的路径,而不是ftl文件的路径
                 */
                //指定路径的第一种方式(根据某个类的相对路径指定)
                //configuration.setClassForTemplateLoading(this.getClass(),"");
                configuration.setClassForTemplateLoading(ToWord.class, "/com/havenliu/document/template");
    
                //指定路径的第二种方式,我的路径是C:/a.ftl
                //configuration.setDirectoryForTemplateLoading(new File("C:\\Users\\张胜强\\Desktop"));
    
                // 输出文档路径及名称
                File outFile = new File("C:\\Users\\张胜强\\Desktop\\"+docName);
    
                //以utf-8的编码读取ftl文件
                Template t = configuration.getTemplate(ftlName, "utf-8");
                Writer out = new BufferedWriter(new OutputStreamWriter(new FileOutputStream(outFile), "utf-8"), 10240);
                t.process(dataMap, out);
                out.close();
            } catch (Exception e) {
                e.printStackTrace();
            }
        }
    }

### 5.编写freemaker代码编辑修改jhj.ftl文件 ,记住map中的两个集合的key jhj1List 和jhj2List ,这个两个遍历要用,子属性也是直接点出来 ###

可以用IDEA打开 然后Ctrl+Alt+L 整理格式宜读

1.单值赋值 直接搜索之前赋值(如111),找到对应的位置,然后编辑 指令为  $\{\}

![watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L3poYW5nc2hlbmdxaWFuZzE2OA_size_16_color_FFFFFF_t_70 6][]

111对应word的是安装位置,现在赋值.json中单独的字段azaddress表示安装位置,这修改为如下,就可以了.

![watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L3poYW5nc2hlbmdxaWFuZzE2OA_size_16_color_FFFFFF_t_70 7][]

2.List遍历赋值.搜索3333找到遍历值位置,行是以上一行的"备注"结尾,然后观察,找到一行的所有数据

![watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L3poYW5nc2hlbmdxaWFuZzE2OA_size_16_color_FFFFFF_t_70 8][]

3.确定位置,然后开始遍历然后赋值, 闭合标签记得放到后面去

![watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L3poYW5nc2hlbmdxaWFuZzE2OA_size_16_color_FFFFFF_t_70 9][]

4.list的子属性.是直接点出来的

![watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L3poYW5nc2hlbmdxaWFuZzE2OA_size_16_color_FFFFFF_t_70 10][]

5.写if 判断,图一简单if ,图2是把字体样式都包含进去了

![watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L3poYW5nc2hlbmdxaWFuZzE2OA_size_16_color_FFFFFF_t_70 11][]

![watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L3poYW5nc2hlbmdxaWFuZzE2OA_size_16_color_FFFFFF_t_70 12][]

6.都赋好值后直接执行main方法就可以生产了

7.freemaker语法指令  :  [https://www.cnblogs.com/Jimc/p/9791507.html][https_www.cnblogs.com_Jimc_p_9791507.html]

8.如果没有集合需要遍历,都是单数据填充,可以推荐easypoi处理,更为简单,参考 [https://www.jianshu.com/p/0a40b90cc72c][https_www.jianshu.com_p_0a40b90cc72c]
