Spring中ClassPathXmlApplication與FileSystemXmlApplicationContext的區別以及ClassPathXmlApplicationContext 的具體路徑

標籤：system   方式   cto   context   sys   resources   test   ffffff   contex   

一、ClassPathXmlApplicationContext 的具體路徑


String s[] = System.getProperty("java.class.path").split(";");
for (String string : s) {
    System.out.println(string);
}

排除掉lib以及C盤的，最後指向的是 ../target/classes/


所以把spring的xml放到main/resources下，Build-->make project（ctrl+F9）一下，即可在target產生，這時候使用以下語句就可以了

ApplicationContext bf = new ClassPathXmlApplicationContext("applicationContext.xml");

二、ClassPathXmlApplicationContext 使用方法

public void testBean(){    //單設定檔方式一    BeanFactory beanFactory=new ClassPathXmlApplicationContext("applicationContext.xml");        //單設定檔方式二    BeanFactory beanFactory=new ClassPathXmlApplicationContext("classpath:applicationContext.xml");        //多個設定檔    BeanFactory beanFactory=new ClassPathXmlApplicationContext(new String[]{"applicationContext.xml"});        //絕對路徑需加“file:”首碼    BeanFactory beanFactory = new ClassPathXmlApplicationContext("file:E:\Workspace\idea_workspace\spring\springtest\src\main\resources\applicationContext.xml");    TestBean bean= (TestBean) beanFactory.getBean("testBean");    assertEquals("testStr",bean.getTestStr());}

　　

三、FileSystemXmlApplicationContext使用方法

public void testBean(){
    //項目根目錄    BeanFactory beanFactory=new FileSystemXmlApplicationContext("applicationContext.xml");

    //classes目錄    BeanFactory beanFactory=new FileSystemXmlApplicationContext("classpath:applicationContext.xml");

    //項目路徑相對路徑    BeanFactory beanFactory=new FileSystemXmlApplicationContext("src\\main\\resources\\applicationContext.xml");    //多設定檔    BeanFactory beanFactory=new FileSystemXmlApplicationContext(new String[]{"src\\main\\resources\\applicationContext.xml"});    //絕對目錄    BeanFactory beanFactory=new FileSystemXmlApplicationContext(new String[]{"E:\\Workspace\\idea_workspace\\spring\\springtest\\src\\main\\resources\\applicationContext.xml"});    TestBean bean= (TestBean) beanFactory.getBean("testBean");    assertEquals("testStr",bean.getTestStr());}
