返回类似 select *from 的做法
过程：
create procedure selectAll()
BEGIN
select * from user;
end
xml配置：
<select id="selectall" resultType="map" statementType="CALLABLE">
{call selectAll()}
</select>
java配置：
//service层调用
List<Map<String, Object>> ss = accountMapper.selectall();
//DAO调用
public List<Map<String,Object>> selectall();

1.java调用传入MAP。获取通过MAP获取。
1.1 mapper文件写法
Xml代码
<parameterMap type="map" id="homeVO">
<parameter property="pcsId" jdbcType="INTEGER" mode="IN"/>
<parameter property="drId" jdbcType="INTEGER" mode="IN"/>
<parameter property="partnerId" jdbcType="INTEGER" mode="IN"/>
<parameter property="customerId" jdbcType="INTEGER" mode="IN"/>
<parameter property="pcsCount" jdbcType="INTEGER" mode="OUT"/>
<parameter property="drCount" jdbcType="INTEGER" mode="OUT"/>
</parameterMap>
<select id="selectForHome" parameterMap="homeVO"
statementType="CALLABLE">
{call selectCount(
?,?,?,?,?,?
)}
</select>
1.2 java调用写法
Java代码
@Override
public StringselectHomeCount(HomeVO home) throws Exception {
Map<String, Object> map = new HashMap<String, Object>();
map.put("pscId", 0);
map.put("drId", 1);
map.put("partnerId", 25);
map.put("customerId", 50);
map.put("isolation", 1);
selectOne("Mapper.selectForHome", map);
System.out.println(map.get("pcsCount"));
return map.get("drCount");
}
