静态化文件位置注意：
实体类定义：
public class news {
private string title;
private string pubtime;
private string category;
private string newscontent;
public string gettitle() {
return title;
}
public void settitle(string title) {
this.title = title;
}
public string getpubtime() {
return pubtime;
}
public void setpubtime(string pubtime) {
this.pubtime = pubtime;
}
public string getcategory() {
return category;
}
public void setcategory(string category) {
this.category = category;
}
public string getnewscontent() {
return newscontent;
}
public void setnewscontent(string newscontent) {
this.newscontent = newscontent;
}
}
自定义流的工具类
public class charstreamio {
public void copyfile(string fsrc,string fdest){
file file = new file(fdest);
if(file.exists()){
file.delete();
}
printwriter out = null;
bufferedreader in = null;
try {
in = new bufferedreader(new filereader(fsrc));
out = new printwriter(new bufferedwriter(new filewriter(fdest)));
string strret;
while((strret=in.readline()) != null){
out.println(strret);
out.flush();
}
} catch (exception e) {
e.printstacktrace();
}finally{
if(in != null){
try {
in.close();
} catch (exception e2) {
e2.printstacktrace();
}
}
if(out != null){
try {
out.close();
} catch (exception e2) {
e2.printstacktrace();
}
}
}
}
/**
* 把传入的信息，保存成文件
* @param finfo 传入的文件内容信息
* @param fname 目标路径和文件名
*/
public void writefile(string finfo,string fdest){
file file = new file(fdest);
if(file.exists()){
file.delete();
}
printwriter out = null;
try {
out = new printwriter(new bufferedwriter(new filewriter(fdest)));
out.write(finfo);
out.flush();
} catch (exception e) {
e.printstacktrace();
}finally{
if(out !=null){
out.close();
}
}
}
/**
* 读取文本型文件
* @param name
* @return
*/
public string readfile(string fname){
file file = new file(fname);
stringbuilder bild = new stringbuilder();
bufferedreader in = null;
if(file.exists()){
try {
in = new bufferedreader(new filereader(fname));
string strret;
while((strret=in.readline()) != null){
bild.append(strret);
}
} catch (exception e) {
e.printstacktrace();
}finally{
if(in != null){
try {
in.close();
} catch (exception e2) {
e2.printstacktrace();
}
}
}
}else{
system.out.println(fname + "不存在");
}
return bild.tostring();
}
}
数据访问层
public class newsdao {
/**
* 读取数据库中要生成的新闻信息
* @return
*/
public list<news> getallnews(){
charstreamio io = new charstreamio();
simpledateformat sd = new simpledateformat("yyyy-mm-dd hh:mm:ss");
list<news> newslist = new arraylist<news>();
news n1 = new news();
n1.setcategory("sport");
string c1 = io.readfile("newsinfo\\news1.txt");
n1.setnewscontent(c1);
n1.setpubtime(sd.format(new date()));
n1.settitle("深足教练组：说我们买球是侮辱 朱广沪常暗中支招");
news n2 = new news();
n2.setcategory("hot");
string c2 = io.readfile("\\newsinfo\\news2.txt");
n2.setnewscontent(c2);
n2.setpubtime(sd.format(new date()));
n2.settitle("对对对发发发失误失误");
newslist.add(n1);
newslist.add(n2);
return newslist;
}
}
业务逻辑层
public class newsbiz {
/**
* 读取数据库中要生成的新闻信息
* @return
*/
public void createallnews() throws exception{
newsdao dao = new newsdao();
list<news> newslist = dao.getallnews();
string destpath = "/news/newspages";
for(int i=0;i<newslist.size();i++){
//读取模板
charstreamio io = new charstreamio();
string tmp = io.readfile("/news/news.tmp");
//替换模板中的参数数据
news n = newslist.get(i);
string newtmp;
newtmp = tmp.replace(templateparam.title, n.gettitle());
newtmp = newtmp.replace(templateparam.category,n.getcategory());
newtmp = newtmp.replace(templateparam.pub_time,n.getpubtime());
newtmp = newtmp.replace(templateparam.content, n.getnewscontent());
//把替换后的内容保存成新闻页面
io.writefile(newtmp, destpath + "/news-" + i + ".html");
}
}
}
templateparam类
public class templateparam {
public static final string title = "%{title}%";
public static final string category = "%{category}%";
public static final string content = "%{newscontent}%";
public static final string pub_time = "%{pubtime}%";
}
用户接口层
public class newstest {
public static void main(string[] args) {
newsbiz biz = new newsbiz();
try {
biz.createallnews();
system.out.println("新闻页面创建完毕！");
} catch (exception e) {
e.printstacktrace();
}
}
}
以上就是html实现页面静态化的案例的详细内容。
