JSON 日期格式處理(JAVA->JSON)

public class JsonDateValueProcessor implements JsonValueProcessor {
    private String format = "yyyy-MM-dd";
    
    public JsonDateValueProcessor() {
        super();
    }
    
    public JsonDateValueProcessor(String format) {
        super();
        this.format = format;
    }
    @Override
    public Object processArrayValue(Object value, JsonConfig jsonConfig) {
        String[] obj = {};
        if (value instanceof Timestamp[]){　　----->Date 類型 Timestamp 全改 Date 16             SimpleDateFormat sf = new SimpleDateFormat(format);
            Timestamp[] dates = (Timestamp[]) value;
            obj = new String[dates.length];
            for (int i=0; i<dates.length; i++){
                obj[i] = sf.format(dates[i]);
            }
        }
        return obj;
    }

    @Override
    public Object processObjectValue(String key, Object value, JsonConfig jsonConfig) {
        if (value instanceof Timestamp) {  
            String str = new SimpleDateFormat(format).format((Timestamp) value);  
            return str;  
        }  
        return value.toString();  
    }

    public String getFormat() {
        return format;
    }

    public void setFormat(String format) {
        this.format = format;
    }

}

使用:　

//日期格式按此進行json轉換
JsonConfig jsonConfig = new JsonConfig();
jsonConfig.registerJsonValueProcessor(Timestamp.class, new JsonDateValueProcessor());

可能異常:(參考:http://www.tuicool.com/articles/2qYfMb)

1. java.lang.NoClassDefFoundError: org/apache/commons/lang/exception/NestableRuntimeException

    解決辦法：需要導入commons-lang-2.5.jar包

2. java.lang.NoClassDefFoundError: org/apache/commons/logging/LogFactory

 

   解決辦法：需要導入 commons-logging-1.1.1.jar 包

3 . java.lang.NoClassDefFoundError: org/apache/commons/collections/map/ListOrderedMap

   解決辦法：需要導入 commons-collections-3.1.jar 包

使用json時需要用到的jar包有以下幾個（版本不限）：

commons-beanutils-1.7.0.jar

commons-collections-3.1.jar

commons-lang-2.5.jar

commons-logging-1.1.1.jar

ezmorph-1.0.3.jar

json-lib-2.2.2-jdk15.jar
