ConfigUtil（配置文件加载操作）

 

纯代码

第一步：配置好配置文件：

 

配置文件置于 框架的 src 下，命名为 application.properties

内容类似于：

#oracle version database settings
#jdbc.driver=oracle.jdbc.driver.OracleDriver
#jdbcjdbc.url=jdbc:oracle:thin:@127.0.0.1:1521:space
#jdbc.username=space
#jdbc.password=space
#hibernate.dialect=org.hibernate.dialect.Oracle10gDialect
###本应用数据库########################################################################
jdbc.driver=com.mysql.jdbc.Driver
jdbcjdbc.url=jdbc:mysql://127.0.0.1:3306/patientfriends?useUnicode=true&characterEncoding=utf-8&zeroDateTimeBehavior=convertToNull&transformedBitIsBoolean=true
jdbc.username=root
jdbc.password=root
hibernate.dialect=org.hibernate.dialect.MySQLDialect
#hibernate settings
hibernate.show_sql=true
hibernate.format_sql=false
#dbcp settings
dbcp.maxIdle=5
dbcp.maxActive=40

 

里面存放框架中所有应该提取出的参数信息，比如：数据库连接信息，定时器时间戳，Email相关参数信息，图片宽高参数，URl，用户名密码等等。

 

第二步：编写 配置文件加载操作类 ConfigUtil

public class ConfigUtil {

    private static PropertiesConfiguration  config=null;
    static{
        try{
            //config = new PropertiesConfiguration("app.properties");
            //config.setEncoding("UTF-8");
            //config.setHeader(header)
            config = new PropertiesConfiguration();
            config.setEncoding("UTF-8");
            config.load("application.properties");

        }catch(Exception ex){
        }
    }


    public static int getIntValue(String key){
        int reInt = 1;
        try{
            //PropertiesConfiguration  config = new PropertiesConfiguration("conf.properties");
            reInt = config.getInt(key);
        }catch(Exception ex){
            ex.fillInStackTrace();
            reInt = 0;
        }
        return reInt;
    }

    public static Long getLongValue(String key) {
        Long reLong = 1l;
        try{
            //PropertiesConfiguration  config = new PropertiesConfiguration("conf.properties");
            reLong = config.getLong(key);
        }catch(Exception ex){
            ex.fillInStackTrace();
            reLong = 0l;
        }
        return reLong;
    }



    public static double getDoubleValue(String key){
        double reDouble = 1.0;
        try{
            //PropertiesConfiguration  config = new PropertiesConfiguration("conf.properties");
            reDouble = config.getDouble(key);
        }catch(Exception ex){
            ex.fillInStackTrace();
            reDouble =1.0;
        }
        return reDouble;
    }

    public static String getStringValue(String key){
        String str = "";
        try{
            //PropertiesConfiguration  config = new PropertiesConfiguration("conf.properties");
            str = config.getString(key);
        }catch(Exception ex){
            ex.fillInStackTrace();
            str = "";
        }
        return str;
    }

    public static Boolean getBooleanValue(String key) {
        Boolean flag = false;
        try{
            flag = config.getBoolean(key);
        }catch(Exception ex){
            ex.fillInStackTrace();
        }
        return flag;
    }

    public static void save(String key,Object o){
        config.setProperty(key, o);
        try{
            //config.save("score.properties");
            config.save("application.properties");
            //config = new PropertiesConfiguration("app.properties");
            config = new PropertiesConfiguration();
            config.setEncoding("UTF-8");
            config.load("application.properties");
        }catch(Exception ex){
            ex.printStackTrace();
        }
    }

    public static void main(String[] args){
        System.out.println("ewew");
        System.out.println(getIntValue("vip.money"));
        //ConfigUtil.save("rmb.money", 20);
        //ConfigUtil.save("month.live", "123334");
        System.out.println(ConfigUtil.getStringValue("month.live1"));
        //System.out.println(getStringValue("month.live"));
    }

    // 读取配置文件
    private static ResourceBundle cache = null;

    static {
        try {
            cache = ResourceBundle.getBundle("application");
        } catch (RuntimeException e) {
            e.printStackTrace();
        }
    }

    /**
     * 功能描述：获取配置文件参数值
     *
     * @param str(参数KEY值)
     * @return
     */
    public static String getValue(String str) {
        String s = cache.getString(str);
        try {
            s = new String(s.getBytes("ISO8859-1"), "utf-8");
        } catch (UnsupportedEncodingException e) {
            e.printStackTrace();
        }
        return s;
    }

    /**
     * 功能描述：获取指定配置文件参数的值
     *
     * @param strPropertiesFile(配置文件名称)
     * @param strItem(参数名称)
     * @return
     */
    public String getPropertiesValue(String strPropertiesFile, String strItem) {
        String strItemValue = "";
        ResourceBundle resources1 = null;
        try {
            resources1 = ResourceBundle.getBundle(strPropertiesFile);
            strItemValue = resources1.getString(strItem);
        } catch (MissingResourceException e) {
            System.out.println("ConfigInfo.getPropertiesValue error:"
                    + e.getMessage());
        }
        return strItemValue;
    }
