springMVC 提交字符串转日期（The request sent by the client was syntactically incorrect.）

pojo:（ createtime是Date类型）

public class Items {
    private Integer id;
    private String name;
    private Float price;
    private String pic;
    private Date createtime;
    private String detail;
    public Integer getId() {
        return id;
    }
    public void setId(Integer id) {
        this.id = id;
    }
    public String getName() {
        return name;
    }
    public void setName(String name) {
        this.name = name == null ? null : name.trim();
    }
    public Float getPrice() {
        return price;
    }
    public void setPrice(Float price) {
        this.price = price;
    }
    public String getPic() {
        return pic;
    }
    public void setPic(String pic) {
        this.pic = pic == null ? null : pic.trim();
    }
    public Date getCreatetime() {
        return createtime;
    }
    public void setCreatetime(Date createtime) {
        this.createtime = createtime;
    }
    public String getDetail() {
        return detail;
    }
    public void setDetail(String detail) {
        this.detail = detail == null ? null : detail.trim();
    }
}

直接提交报错：

解决：

在springmvc.xml文件中：

<!-- 注解驱动 -->
        <mvc:annotation-driven conversion-service="conversionServiceFactoryBean"/>
        <!-- <mvc:annotation-driven/> -->
        <!-- 配置Conveter转换器  转换工厂  -->
        <bean id="conversionServiceFactoryBean" class="org.springframework.format.support.FormattingConversionServiceFactoryBean">
            <property name="converters">
                <list>
                    <bean class="com.it.springmvc.conversion.DateConveter"/>
                </list>
            </property>
        </bean>

DateConveter.java:

public class DateConveter implements Converter<String, Date>{
    public Date convert(String dateStr) {
        try {
            if(dateStr != null && dateStr != ""){
                // 把字符串转换为日期类型
                SimpleDateFormat simpleDateFormat = new SimpleDateFormat("yyy-MM-dd HH:mm:ss");
                return simpleDateFormat.parse(dateStr);
            }
        } catch (Exception e) {
            e.printStackTrace();
        }
        return null;
    }
}
