Generate html files using java

The principle is similar to using Java to generate jsp servlet. We can use printStream to output data to html files.

First create a StringBuilder object and add html statements to it through the append method. As shown in the following example:

StringBuilder sb = new StringBuilder();  
        Properties fileProperties = getProperties("file");  
        Properties sqlProperties = getProperties("sql");  
        PrintStream printStream = new PrintStream(new FileOutputStream(  
                "report.html"));  
        sb.append("<html>");  
        sb.append("<head>");  
        sb.append("<title>每日运营报表</title>");  
        sb.append("<meta http-equiv=\"Content-Type\" content=\"text/html; charset=utf-8\" />");  
        sb.append("<style type=\"text/css\">");  
        sb.append("TABLE{border-collapse:collapse;border-left:solid 1 #000000; border-top:solid 1 #000000;padding:5px;}");  
        sb.append("TH{border-right:solid 1 #000000;border-bottom:solid 1 #000000;}");  
        sb.append("TD{font:normal;border-right:solid 1 #000000;border-bottom:solid 1 #000000;}");  
        sb.append("</style></head>");  
        sb.append("<body bgcolor=\"#FFF8DC\">");  
        sb.append("<div align=\"center\">");  
        sb.append("<br/>");  
        sb.append("<br/>");  
        List<Map<String, Object>> result1 = getRpt(sqlProperties  
                .getProperty("sql1"));  
        for (Map.Entry<String, Object> m : result1.get(0).entrySet()) {  
            sb.append(fileProperties.getProperty("file1"));  
            sb.append(m.getValue());  
        }  
        sb.append("<br/><br/>");

The output is also very simple.

sb.append("</div></body></html>");  
        printStream.println(sb.toString());

Upload another test html that I generated using java, but the online data has not been called yet. In practical applications, you can use sql statements and lists to fill tables.

Here is an example I wrote

sb.append("<table border=\"1\"><tr>");  
        for (Map.Entry<String, Object> m : result.get(0).entrySet()) {  
            sb.append("<th>");  
            sb.append(m.getKey());  
            sb.append("</th>");  
        }  
        sb.append("</tr>");  
        for (int i = 0; i < result.size(); i++) {  
            sb.append("<tr>");  
            for (Map.Entry<String, Object> m : result.get(i).entrySet()) {  
                sb.append("<td>");  
                sb.append(m.getValue());  
                sb.append("</td>");  
            }  
            sb.append("</tr>");  
        }  
        sb.append("</table>");
