1.配置springMVC可以接收json字符串

<?xml version="1.0" encoding="UTF-8"?>

    	<bean 
    		class="org.springframework.web.servlet.mvc.method.annotation.RequestMappingHandlerAdapter">
    		<property name="messageConverters">
    			<list>
    				
    				<bean 
    					class="org.springframework.http.converter.json.MappingJacksonHttpMessageConverter">
    					<property name="supportedMediaTypes">
    						<list>
    							<value>application/json;charset=UTF-8</value>
    						</list>
    					</property>
    				</bean>
    			</list>
    		</property>
    	</bean>
    	
    	<context:component-scan base-package="com.mvc.action"></context:component-scan>
    	<bean class="org.springframework.web.servlet.view.InternalResourceViewResolver"
    		p:viewClass="org.springframework.web.servlet.view.JstlView"
    		p:prefix="/"
    		p:suffix=".jsp">
    	</bean>
    	
    	
    	<context:annotation-config/>
    	<mvc:annotation-driven/>
    </beans>

2.@Controller类代码

@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;
    
    /**
     * 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

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。
