复制提示
spring参数绑定时可能出现 BindException(参数绑定异常),类似下面的日期绑定异常(前台传过来是String类型,实际的pojo是Date类型)
default message [Failed to convert property value of type 'java.lang.String' to required type 'java.util.Date' for property 'endTime';
nested exception is org.springframework.core.convert.ConversionFailedException: Unable to convert value "2016-01-31" from type 'java.lang.String' to type 'java.util.Date';
自定义Converter
public class CustomDateConverter implements Converter<String, Date> { @Override
public Date convert(String source) {
try {
SimpleDateFormat simpleDateFormat = new SimpleDateFormat("yyyy-MM-dd HH:mm:ss");
return simpleDateFormat.parse(source);
} catch (Exception e) {
e.printStackTrace();
}
return null;
}}
springmvc.xml配置
<mvc:annotation-driven conversion-service="conversionService">
</mvc:annotation-driven>
<!-- conversionService -->
<bean id="conversionService"
class="org.springframework.format.support.FormattingConversionServiceFactoryBean">
<!-- 转换器 -->
<property name="converters">
<list>
<bean class="com.xxx.xxx.converter.CustomDateConverter"/>
</list>
</property>
</bean>
pojo的日期属性注入
@DateTimeFormat(pattern = "yyyy-MM-dd HH:mm:ss")
private Date startTime;
