1.配置springMVC可以接收json字符串

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。
