苦逼逗逼二逼
以页面title举例:
读取多语言肯定要放在properties中，并且通过后台读取properties对应的键返回其值，则jsp页面需要引入类:
<%@page import="com.mytest.sys.config.systextconfig"%> <%@page import="com.mytest.sys.config.systextconfig"%>这里systextconfig类处理多语言
<title><%=systextconfig.getconfiginfo("bsd_text")+systextconfig.getconfiginfo("title")%></title>
<title><%=systextconfig.getconfiginfo("bsd_text")+systextconfig.getconfiginfo("title")%></title>
systextconfig类的内容为
public class systextconfig {
private static properties properties =null;//读取properties的资源文件
private static long lastmodified=0;//内存中上次修改的时间 long型
private static string filepath=null;//保存properties文件的绝对路径
private static file sysconfigfile=null;
static {//初始化static变量的值
stringbuffer configfilepath = new stringbuffer();
string classpath= systextconfig.class.getclassloader().getresource("").getpath();
string weninfopath = classpath.substring(0,classpath.lastindexof("classes"));
configfilepath.append(weninfopath).append("config");
configfilepath.append(file.separator).append("systext.properties");
filepath=configfilepath.tostring();
}
private static boolean isnotlastmodified(){
sysconfigfile= new file(filepath);
if( sysconfigfile.lastmodified()!=lastmodified)
return true;
return false;
}
private static void loadsysconfigfile(){
properties = new properties();
fileinputstream fileinputstream;
try {
fileinputstream = new fileinputstream(sysconfigfile);
properties.load(fileinputstream);
} catch (exception e) {
// todo auto-generated catch block
e.printstacktrace();
}
}
public static string getconfiginfo(string key) {
//函数入口,首先校验properties文件的最近以次修改时间，如果不为0 则代表其修改过 则要再次加载loadsysconfigfile
if(isnotlastmodified()) loadsysconfigfile();
object object = properties.get(key); //读取properties的键
string value ="";
try {
if(stringutils.isnotempty(object)){
value = new string(object.tostring().getbytes("iso8859_1"));//通过键返回其值
}
} catch (unsupportedencodingexception e) {
e.printstacktrace();

return value;
