@RequestBody接收json字符串,自动将日期字符串转换为java.util.Date

1.配置springMVC可以接收json字符串

@RequestMapping(value="/addDicAppUsers.do")
@ResponseBody
public boolean addDicAppUsers(@RequestBody DicAppUsersModel dicAppUsersModel)
{
if(dicAppUsersService.addDicAppUsers(dicAppUsersModel))
{
return true;
}
else
{
return false;
}
}3.实体类对象代码
package com.mvc.model;

import java.util.Date;
import org.codehaus.jackson.map.annotate.JsonDeserialize;
import org.codehaus.jackson.map.annotate.JsonSerialize;
import com.mvc.imp.DateJsonDeserializer;
import com.mvc.imp.DateJsonSerializer;

/**

@SuppressWarnings("serial")
public class DicAppUsersModel implements java.io.Serializable
{
private long id;
private String loginid;
private String loginname;
private String loginpassword;
private String loginunitcode;
private String workplace;
@JsonSerialize(using=DateJsonSerializer.class)
@JsonDeserialize(using=DateJsonDeserializer.class)
private Date addtime;
private long sourceid;
@JsonSerialize(using=DateJsonSerializer.class)
@JsonDeserialize(using=DateJsonDeserializer.class)
private Date createdate;
public DicAppUsersModel() {
super();
}
public DicAppUsersModel(long id, String loginid, String loginname,
String loginpassword, String loginunitcode, String workplace,
Date addtime, long sourceid, Date createdate) {
super();
this.id = id;
this.loginid = loginid;
this.loginname = loginname;
this.loginpassword = loginpassword;
this.loginunitcode = loginunitcode;
this.workplace = workplace;
this.addtime = addtime;
this.sourceid = sourceid;
this.createdate = createdate;
}
public long getId() {
return id;
}
public void setId(long id) {
this.id = id;
}
public String getLoginid() {
return loginid;
}
public void setLoginid(String loginid) {
this.loginid = loginid;
}
public String getLoginname() {
return loginname;
}
public void setLoginname(String loginname) {
this.loginname = loginname;
}
public String getLoginpassword() {
return loginpassword;
}
public void setLoginpassword(String loginpassword) {
this.loginpassword = loginpassword;
}
public String getLoginunitcode() {
return loginunitcode;
}
public void setLoginunitcode(String loginunitcode) {
this.loginunitcode = loginunitcode;
}
public String getWorkplace() {
return workplace;
}
public void setWorkplace(String workplace) {
this.workplace = workplace;
}
public Date getAddtime() {
return addtime;
}
public void setAddtime(Date addtime) {
this.addtime = addtime;
}
public long getSourceid() {
return sourceid;
}
public void setSourceid(long sourceid) {
this.sourceid = sourceid;
}
public Date getCreatedate() {
return createdate;
}
public void setCreatedate(Date createdate) {
this.createdate = createdate;
}
}4.DateJsonSerializer类代码
package com.mvc.imp;

import java.io.IOException;
import java.text.SimpleDateFormat;
import java.util.Date;
import org.codehaus.jackson.JsonGenerator;
import org.codehaus.jackson.JsonProcessingException;
import org.codehaus.jackson.map.JsonSerializer;
import org.codehaus.jackson.map.SerializerProvider;

public class DateJsonSerializer extends JsonSerializer<Date>
{
public static final SimpleDateFormat format=new SimpleDateFormat("yyyy-MM-dd HH:mm:ss");
public void serialize(Date date,JsonGenerator jsonGenerator,SerializerProvider serializerProvider)
throws IOException,JsonProcessingException
{
jsonGenerator.writeString(format.format(date));
}
}5.DateJsonDeserializer类代码
package com.mvc.imp;

import java.io.IOException;
import java.text.SimpleDateFormat;
import java.util.Date;
import org.codehaus.jackson.JsonParser;
import org.codehaus.jackson.JsonProcessingException;
import org.codehaus.jackson.map.DeserializationContext;
import org.codehaus.jackson.map.JsonDeserializer;

public class DateJsonDeserializer extends JsonDeserializer<Date>
{
public static final SimpleDateFormat format=new SimpleDateFormat("yyyy-MM-dd HH:mm:ss");
public Date deserialize(JsonParser jsonParser,DeserializationContext deserializationContext)
throws IOException,JsonProcessingException
{
try
{
return format.parse(jsonParser.getText());
}
catch(Exception e)
{
System.out.println(e.getMessage());
throw new RuntimeException(e);
}
}
}这样，就可以把接收到的json日期字符串转换为Date了。后面，就可以直接通过Date类型保存日期数据了。
