2.@Controller类代码

[java] view
plain copy

@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

[java] view
plain copy

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;  

  

/** 

 * 用户视图类 

 * @author suyunlong 

 * 

 */  

@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

[java] view
plain copy

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

[java] view
plain copy

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。
