异常信息如下:

看异常信息大概知道属性wfsj这个字段,不能完成java.util.Date 到 java.sql.Timestamp 日期时间戳的转换。后面还有提示, 没有找到匹配的conversion或editor。
conversion 在Spring中转换对象属性会用到,而editor和converter 以及formatter也是在转换对象(String –> Date, String –> Timestamp),从字符串到对象,从对象到字符串的时候会经常用到。
解决方法:
<bean id="customConfigProcessor" class="com.jp.tic.framework.flex.converter.CustomAmfConversionServiceConfigProcessor"/><flex:message-broker services-config-path="/WEB-INF/flex/services-config.xml"><flex:exception-translator ref="flexExceptionTranslator" /><flex:config-processor ref="configProcessor"/><flex:config-processor ref="customConfigProcessor"/><!--<flex:message-interceptor ref="flexMessageInterceptor" /><flex:message-interceptor ref="loginMessageInterceptor" />--></flex:message-broker>为message-broker对象注入CustomAmfConversionServiceConfigProcessor对象,CustomAmfConversionServiceConfigProcessor是继承AbstractAmfConversionServiceConfigProcessor对象。
AbstractAmfConversionServiceConfigProcessor对象中提供了对各个类型转换serialization/deserialization的方法。
package com.jp.tic.framework.flex.converter;import java.util.HashSet;import java.util.Set;import org.springframework.flex.core.io.AbstractAmfConversionServiceConfigProcessor;/*** <b>function:</b> 自定义AMF转换服务* @author hoojo* @createDate 2013-7-17 下午01:35:12* @file CustomAmfConversionServiceConfigProcessor.java* @package com.jp.tic.framework.flex.converter* @project JTZHJK-Server* @blog http://blog.csdn.net/IBM_hoojo* @email hoojo_@126.com* @version 1.0*/public class CustomAmfConversionServiceConfigProcessor extends AbstractAmfConversionServiceConfigProcessor {private static Set<Class<?>> classes = new HashSet<Class<?>>();@Overrideprotected Set<Class<?>> findTypesToRegister() {return classes;}}
如果你还需要添加更多自己的转化服务,那么你需要给CustomAmfConversionServiceConfigProcessor 注入conversionService对象。
<!-- 添加配置类型转换器、转换服务 --><bean id="conversionService" class="org.springframework.format.support.FormattingConversionServiceFactoryBean"><property name="converters"><list><bean class="com.jp.tic.framework.mvc.convert.StringToTimestampConverter"/><bean class="com.jp.tic.framework.mvc.convert.DateToTimestampConverter"/></list></property><property name="formatters"><list><bean class="com.jp.tic.framework.mvc.formatter.SimpleDateTimeFormatAnnotationFormatterFactory"/><bean class="com.jp.tic.framework.mvc.formatter.TimestampFormatterFactory"/></list></property></bean>
