我正在尝试从src/java/Gender.java类中定义的Java POJO中使用i18n国际化。

Gender类:

public enum Gender { 
 
  NONE(0), 
  MALE(1), 
  FEMALE(2); 
 
  private Integer code; 
 
  Gender(final Integer code) { 
    this.code = code; 
  } 
 
  Integer code() { 
    return code; 
  } 
 
} 

public enum Gender { 
 
  NONE(0, message("gender.none")), 
  MALE(1, message("gender.male")), 
  FEMALE(2, message("gender.female")); 
 
  private Integer code; 
  private String text; 
 
  Gender(final Integer code, final String text) { 
    this.code = code; 
    this.text = text; 
  } 
 
  Integer code() { 
    return code; 
  } 
 
  Integer text() { 
    return text; 
  } 
 
} 

请您参考如下方法:

您可以使用toString()方法和messageSource bean从enum获取messages.properties文本值，例如:

import grails.util.Holders; 
import org.codehaus.groovy.grails.web.servlet.mvc.GrailsWebRequest; 
import org.codehaus.groovy.grails.web.util.WebUtils; 
import org.springframework.context.MessageSource; 
 
public enum Gender { 
 
    NONE(0, "none"), 
    MALE(1, "male"), 
    FEMALE(2, "female"); 
 
    MessageSource messageSource = (MessageSource) Holders.getApplicationContext().getBean("messageSource"); 
    private Integer code; 
    private String text; 
 
    Gender(final Integer code, final String text) { 
        this.code = code; 
        this.text = text; 
    } 
 
    Integer code() { 
        return code; 
    } 
 
    String text() { 
        return text; 
    } 
 
    @Override 
    public String toString() { 
        GrailsWebRequest webUtils = WebUtils.retrieveGrailsWebRequest(); 
        return messageSource.getMessage("gender." + text, null, "default", webUtils.getLocale()); 
    } 
} 

gender.none=None 
gender.male=Male 
gender.female=Female
