在Spring中更新屬性文件中的數據庫設置

[英]Update database settings in properties file in Spring

 原文  2010-12-25 11:55:57  4   2    java/ spring/ jsf

問題描述

我剛接觸Spring，我試圖創建一個Database Manager頁面，該頁面顯示頁面加載時的數據庫詳細信息，並在用戶按Submit時更新數據庫設置。

我遵循了本教程，並在屬性文件中設置了數據庫設置。

我設法以編程方式更新了屬性文件中的數據庫設置。 當我使用以下代碼檢索數據庫設置時 

DriverManagerDataSource databaseSource = (DriverManagerDataSource)context.getBean("dataSource");
databaseSource.getUsername();

我設法獲得了舊的價值而無法獲得新的價值

這是applicationContext.xml文件中的映射 

<bean
    class="org.springframework.beans.factory.config.PropertyPlaceholderConfigurer">

    <property name="location">
        <value>classpath:/bundle/database.properties</value>
    </property>
</bean>

<bean id="dataSource"
    class="org.springframework.jdbc.datasource.DriverManagerDataSource">

    <property name="driverClassName" value="${jdbc.driverClassName}" />
    <property name="url" value="${jdbc.url}" />
    <property name="username" value="${jdbc.username}" />
    <property name="password" value="${jdbc.password}" />
</bean>

我檢查了屬性文件，發現它已使用最新輸入進行更新。

我想念什么？

提前致謝

PS我在Spring 3中使用JSF1.2

更新

只是使我的要求簡單。 我正在創建一個setparate dbsettings頁面，以便當用戶希望連接到其他數據庫時，他/她只需在dbsettings頁面中輸入詳細信息並連接

更新

我使用此代碼來檢索應用程序上下文 

private ApplicationContext context;

.... 

ServletContext servletContext = FacesUtil.getServletContext();
    this.context = WebApplicationContextUtils
            .getRequiredWebApplicationContext(servletContext);

如果將其更改為AbstractApplicationContext，則在上面的代碼中需要什么更改？

UPDATE 

this.context = (AbstractApplicationContext)WebApplicationContextUtils
            .getRequiredWebApplicationContext(servletContext);
    String valueForTheProperty = "";


    context.refresh();

當我在上面添加行時

當我注釋掉該行時 

context.refresh()

應用程序運行正常。 請幫助

UPDATE

DBSettingBean 

public DbSettingsBean()
{
    dbSettingsDelegate = new DbSettingsDelegate();

    loadDatabaseSettings();
    submitButton.setRendered(false);
    testButton.setRendered(true);
}

public void loadDatabaseSettings()
{
    this.setUserName(dbSettingsDelegate.getDatabaseUserNameFromSettings());
    this.setPassword(dbSettingsDelegate.getDatabasePassswordFromSettings());
    this.setServerName(dbSettingsDelegate.getDatabaseServerNameFromSettings());
    this.setDataSourceName(dbSettingsDelegate.getDatabaseNameFromSettings());
}

public HtmlOutputText getText()
{
    return text;
}



public void setText(HtmlOutputText text)
{
    this.text = text;
}



public HtmlAjaxCommandButton getSubmitButton()
{
    return submitButton;
}



public void setSubmitButton(HtmlAjaxCommandButton submitButton)
{
    this.submitButton = submitButton;
}



public HtmlCommandButton getTestButton()
{
    return testButton;
}



public void setTestButton(HtmlCommandButton testButton)
{
    this.testButton = testButton;
}



public HtmlOutputText getStatusMessageComponent()
{
    return statusMessageComponent;
}

public void setStatusMessageComponent(HtmlOutputText statusMessageComponent)
{
    this.statusMessageComponent = statusMessageComponent;
}

public UIInput getPassworder()
{
    return passworder;
}

public void setPassworder(UIInput passworder)
{
    this.passworder = passworder;
}

public String getServerName()
{
    return serverName;
}

public void setServerName(String serverName)
{
    this.serverName = serverName;
}

public String getDataSourceName()
{
    return dataSourceName;
}

public void setDataSourceName(String dataSourceName)
{
    this.dataSourceName = dataSourceName;
}

public String getUserName()
{
    return userName;
}

public void setUserName(String userName)
{
    this.userName = userName;
}

public String getPassword()
{
    return password;
}

public void setPassword(String password)
{
    this.password = password;
}

public String testWhetherTheConnectionExists()
{       
    return dbSettingsDelegate.checkWhetherDatabaseConnectionExists(getUserName(), getPassword(), getDataSourceName(),getServerName());
}

和..

DbSettingsDelegate 

public DbSettingsDelegate()
{
    try 
    {
        System.out.println("Dbsettings delegate: "+FacesContext.getCurrentInstance());
        dbSettingsService = (DbSettingsService) ServiceLocator
                        .getInstance().getService(
                        ServiceLocator.Services.DBSETTINGS);
    } 
    catch (Exception e) 
    {
        logger.debug("error in AddressBookDelegate constructor", e);
    }
}

public String getDatabaseUserNameFromSettings()
{
    return dbSettingsService.getDatabaseUserNameFromSettings();
}

public String getDatabasePassswordFromSettings()
{
    return dbSettingsService.getDatabasePasswordFromSettings();
}

public String getDatabaseServerNameFromSettings()
{
    return dbSettingsService.getDatabaseServerNameFromSettings();
}

public String getDatabaseNameFromSettings()
{
    return dbSettingsService.getDatabaseNameFromSettings();
}

public String checkWhetherDatabaseConnectionExists(String theUserName,String thePassword,String theDatabaseName,String theServerName)
{
    return dbSettingsService.checkWhetherTheDatabaseConnectionExists(theUserName, thePassword, theDatabaseName, theServerName);
}

這是檢索數據庫詳細信息以顯示給用戶的代碼 

ServletContext servletContext = FacesUtil.getServletContext();
    this.context = (AbstractApplicationContext)WebApplicationContextUtils
            .getRequiredWebApplicationContext(servletContext);
    String valueForTheProperty = "";
    DriverManagerDataSource databaseSource =  null;

    context.refresh();
    databaseSource = (DriverManagerDataSource)context.getBean("dataSource");



    if(theProperty.equalsIgnoreCase("username"))
    {
        valueForTheProperty = databaseSource.getUsername();
    }       
    else if(theProperty.equalsIgnoreCase("password"))
    {
        valueForTheProperty = databaseSource.getPassword();
    }
    else if(theProperty.equalsIgnoreCase("server"))
    {           
        valueForTheProperty = this.splitUrlAndGetValueForKey(databaseSource.getUrl(), "server");
        System.out.println("Server:  "+valueForTheProperty);
    }
    else
    {
        valueForTheProperty = this.splitUrlAndGetValueForKey(databaseSource.getUrl(), "databasename");
    }

更新當我調試代碼時，我在控制台中找到了這些行。 調用context.refresh() 

Dec 28, 2010 3:22:44 PM org.hibernate.tool.hbm2ddl.SchemaUpdate execute
INFO: Running hbm2ddl schema update
Dec 28, 2010 3:22:44 PM org.hibernate.tool.hbm2ddl.SchemaUpdate execute

INFO: updating schema
Dec 28, 2010 3:22:44 PM org.hibernate.tool.hbm2ddl.SchemaUpdate execute
INFO: schema update complete

因此，我可以假設進行了一些更新。 無法確定我為什么繼續獲得舊價值

context.refresh（）刷新了我認為的整個applicationContext bean。 好的，現在我刪除了它們之間的代理和服務，應用程序現在直接調用

我現在不使用DBSettingsDelegate

UPDATE

更新屬性文件代碼 

Properties properties = new Properties();
    String a = Thread.currentThread()
                .getContextClassLoader()
                .getResource("/com/smartcall/bundle/database.properties").getFile();

    a = a.replaceAll("%20", " ");
    String url = "";

        url = "jdbc:mysql://"+theServerName+":3306/"+theDatabaseName+"?characterEncoding=UTF-8";
        File file = new File(a);
        //file.setWritable(true);

        System.out.println(url);
        System.out.println(file.getAbsolutePath());

        FileInputStream stream = new FileInputStream(file);
        properties.load(stream);

        properties.put("jdbc.username", theUserName);
        properties.put("jdbc.password", thePassword);
        properties.put("jdbc.url", url);            

        properties.store(new FileOutputStream(file),null);

2 個解決方案

解決方案1
 2 已采納  2010-12-25 12:42:09

您需要刷新 Application上下文並再次獲取bean DriverManagerDataSource ，以反映寫入屬性文件的更改。 

context.refresh();
DriverManagerDataSource databaseSource = (DriverManagerDataSource)context.getBean("dataSource");
databaseSource.getUsername();

獲取資源文件對象的提示： 

    URI a = getClass().getResource("/com/smartcall/bundle/database.properties").toURI();
    File file = new File(a);

您無需解碼路徑，即用“”替換％20。 Referrence

在啟動應用程序時讀取值，將它們設置為目標對象（在您的情況下為數據源），並且不再讀取屬性文件。 因此，即使您更改值，它們也不會在任何地方反映出來。

為了讓PropertyPlaceholderConfigurer重新加載值，您必須擴展它並指定重新加載時間。 但這仍然不會更新數據源。 您還應該擴展數據源類，並使其在給定間隔后重新讀取屬性。 或者，您可以將DataSource聲明為作用域prototype ，以便每次獲取一個新實例，然后重新加載屬性。

這是如果您不想重新啟動整個上下文（這可能需要很多時間）
