Spring注入Date类型的三种方法总结
测试Bean:
public class DateBean { private Date birthday; public Date getBirthday() { return birthday; } public void setBirthday(Date birthday) { this.birthday = birthday; } }
方式1:利用SimpleDateFormat的构造方法注入
方式2:纯配置,先自定义CustomDateEditor,再转换类型
方式3:先用一个类重写PropertyEditorSupport的setAsText方法,再在配置文件中,配置转换类型就可以了,跟上面方法类似
public class MyDatePropertyEditor extends PropertyEditorSupport { private String format; public String getFormat() { return format; } public void setFormat(String format) { this.format = format; } // text为需要转换的值,当为bean注入的类型与编辑器转换的类型匹配时就会交给setAsText方法处理 public void setAsText(String text) throws IllegalArgumentException { SimpleDateFormat sdf = new SimpleDateFormat(format); try { this.setValue(sdf.parse(text)); } catch (ParseException e) { e.printStackTrace(); } } }
测试:
public class DateTest { @Test public void testName() throws Exception { ApplicationContext context = new ClassPathXmlApplicationContext( "applicationContext.xml"); DateBean bean = (DateBean) context.getBean("datebean"); System.out.println(bean.getBirthday()); } }
