1.action的写法：
开头写包，
然后在类中写
private static final long serialVersionUID = 3791581176290177353L;
private String MEDIA_ID;
private String MEDIA_NAME;
private String MEDIA_DOMAIN;
private String MEDIA_TYPE;
@Resource
private MediaManageBPO mediaManageBPO;
/**
* 获取所有数据库中媒体的信息
* @return
*/
@Action(value="getMediaInfo")
public String getMediaInfo(){
//定义一个列表，列表中保存多个map对象
List<Map<String,Object>> rsList = new ArrayList<Map<String,Object>>();
rsList = mediaManageBPO.getMediaInfo();
outputJson(rsList);
return NONE;
}
/**
* 查询数据库中媒体的信息
* @return
*/
@Action(value="searchMediaInfo")
public String searchMediaInfo(){
//定义一个map，保存多个键值对
Map<String,Object> argMap = new HashMap<String,Object>();
argMap.put("MEDIA_ID", MEDIA_ID);
argMap.put("MEDIA_NAME", MEDIA_NAME);
argMap.put("MEDIA_DOMAIN", MEDIA_DOMAIN);
argMap.put("MEDIA_TYPE", MEDIA_TYPE);
//定义一个列表，列表中保存多个map对象
List<Map<String,Object>> rsList = new ArrayList<Map<String,Object>>();
rsList = mediaManageBPO.searchMediaInfo(argMap);
outputJson(rsList);
return NONE;
}
/**
* 添加数据库中媒体的信息
* @return
*/
@Action(value="addMediaInfo")
public String addMediaInfo(){
//定义一个map，保存多个键值对
Map<String,Object> argMap = new HashMap<String,Object>();
argMap.put("MEDIA_ID", MEDIA_ID);
argMap.put("MEDIA_NAME", MEDIA_NAME);
argMap.put("MEDIA_DOMAIN", MEDIA_DOMAIN);
argMap.put("MEDIA_TYPE", MEDIA_TYPE);
//定义一个列表，列表中保存多个map对象
mediaManageBPO.addMediaInfo(argMap);
outputString("SUCCESS");
return NONE;
}
/**
* 删除数据库中媒体的信息
* @return
*/
@Action(value="removeMediaInfo")
public String removeMediaInfo(){
//定义一个map，保存多个键值对
Map<String,Object> argMap = new HashMap<String,Object>();
argMap.put("MEDIA_ID", MEDIA_ID);
argMap.put("MEDIA_NAME", MEDIA_NAME);
argMap.put("MEDIA_DOMAIN", MEDIA_DOMAIN);
argMap.put("MEDIA_TYPE", MEDIA_TYPE);
//定义一个列表，列表中保存多个map对象
mediaManageBPO.removeMediaInfo(argMap);
outputString("SUCCESS");
return NONE;
}
/**
* 修改数据库中媒体的信息
* @return
*/
@Action(value="editMediaInfo")
public String editMediaInfo(){
//定义一个map，保存多个键值对
Map<String,Object> argMap = new HashMap<String,Object>();
argMap.put("MEDIA_ID", MEDIA_ID);
argMap.put("MEDIA_NAME", MEDIA_NAME);
argMap.put("MEDIA_DOMAIN", MEDIA_DOMAIN);
argMap.put("MEDIA_TYPE", MEDIA_TYPE);
//定义一个列表，列表中保存多个map对象
mediaManageBPO.editMediaInfo(argMap);
outputString("SUCCESS");
return NONE;
}
public String getMEDIA_ID() {
return MEDIA_ID;
}
public void setMEDIA_ID(String mEDIA_ID) {
MEDIA_ID = mEDIA_ID;
}
public String getMEDIA_NAME() {
return MEDIA_NAME;
}
public void setMEDIA_NAME(String mEDIA_NAME) {
MEDIA_NAME = mEDIA_NAME;
}
public String getMEDIA_DOMAIN() {
return MEDIA_DOMAIN;
}
public void setMEDIA_DOMAIN(String mEDIA_DOMAIN) {
MEDIA_DOMAIN = mEDIA_DOMAIN;
}
public String getMEDIA_TYPE() {
return MEDIA_TYPE;
}
public void setMEDIA_TYPE(String mEDIA_TYPE) {
MEDIA_TYPE = mEDIA_TYPE;
}
2.写bpo
@Resource
MediaManageMapper mediaManageMapper;
//获取媒体信息
public List<Map<String, Object>> getMediaInfo() {
return mediaManageMapper.getMediaInfo();
}
//查询媒体信息
public List<Map<String, Object>> searchMediaInfo(Map<String, Object> argMap) {
return mediaManageMapper.searchMediaInfo(argMap);
}
//添加媒体信息
public void addMediaInfo(Map<String, Object> argMap) {
mediaManageMapper.addMediaInfo(argMap);
}
//删除媒体信息
public void removeMediaInfo(Map<String, Object> argMap) {
mediaManageMapper.removeMediaInfo(argMap);
}
//修改媒体信息
public void editMediaInfo(Map<String, Object> argMap) {
mediaManageMapper.editMediaInfo(argMap);
}
3.写mapper
public interface MediaManageMapper {
//获取媒体信息
List<Map<String, Object>> getMediaInfo();
//查询媒体信息
List<Map<String, Object>> searchMediaInfo(Map<String, Object> argMap);
//添加媒体信息
void addMediaInfo(Map<String, Object> argMap);
//删除媒体信息
void removeMediaInfo(Map<String, Object> argMap);
//修改媒体信息
void editMediaInfo(Map<String, Object> argMap);
}
4.写xml
<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE mapper PUBLIC "-//mybatis.org//DTD Mapper 3.0//EN"
"http://mybatis.org/dtd/mybatis-3-mapper.dtd">
<!-- 引入mapper namespace-->

<!-- SQL查询语句 ，获取表的所有内容-->
<select id="getMediaInfo" parameterType="map" resultType="map">

</if>
<if test="MEDIA_TYPE!=null and MEDIA_TYPE!=‘‘">

</if>
</where>
</select>
<!-- SQL插入语句 ，输入输出参数类型都定义为map类型-->
<insert id="addMediaInfo" parameterType="map" >
insert into wpgl.wp_assess_media t (t.MEDIA_ID,t.MEDIA_NAME,t.MEDIA_DOMAIN,t.MEDIA_TYPE)
values(#{MEDIA_ID},#{MEDIA_NAME},#{MEDIA_DOMAIN},#{MEDIA_TYPE})
</insert>
<!-- SQL删除语句 ，输入输出参数类型都定义为map类型-->
<delete id="removeMediaInfo" parameterType="map" >
delete from wpgl.wp_assess_media t
<where>
<if test="MEDIA_NAME!=null and MEDIA_NAME!=‘‘">

</if>
</where>
</delete>
<!-- SQL修改语句 ,输入输出参数类型都定义为map类型-->
<update id="editMediaInfo" parameterType="map" >
update wpgl.wp_assess_media t
<set>
<if test="MEDIA_NAME!=null and MEDIA_NAME!=‘‘">
t.MEDIA_NAME = #{MEDIA_NAME} ,
</if>
<if test="MEDIA_DOMAIN!=null and MEDIA_DOMAIN!=‘‘">

</if>

</update>
</mapper>
