springboot+mybatis调用oracle存储过程

1 存储过程参数为VARCHAR

代码逻辑：controller层定义实体类对象entity，并entity.set给存储过程的输入参数赋值，把赋值后的实体类通过service层传到dao层，然后通过dao层调用存储过程

1-1 存储过程参数

IN_STR IN VARCHAR, OUT_STR OUT VARCHAR View Code

1-2 controller层

@RequestMapping("/TESTPRO") @ResponseBody public String TESTPRO() {// 执行oracle存储过程// 实体类中把输入参数输出参数都写上//少写参数会报错：(wrong number or types of arguments in call to '存储过程')HelloProEntity entity = new HelloProEntity();entity.setIN_STR("1");// 配置输入参数controllerService.GetTestPro(entity);// 把带输入参数的实体传到Service层，Service层调用Dao层，Dao层寻找实体对应的sqltry {String str = entity.getOUT_STR();return str;} catch (Exception e) {return "null";} } View Code

 1-3 service层

public HelloProEntity GetTestPro(HelloProEntity testproentity) {return dao.GetTestPro(testproentity); } View Code

1-4 dao层

public HelloProEntity GetTestPro(HelloProEntity testproentity); View Code

1-5 实体类

public class HelloProEntity implements Serializable {private static final long serialVersionUID = -6556793741331167103L;private String IN_STR;private String OUT_STR;public String getIN_STR() {return IN_STR;}public void setIN_STR(String iN_STR) {IN_STR = iN_STR;}public String getOUT_STR() {return OUT_STR;}public void setOUT_STR(String oUT_STR) {OUT_STR = oUT_STR;}} View Code

1-6 mapper

<select id="GetTestPro" parameterType="com.kh.zzkanban1.Entyties.HelloProEntity" useCache="false"statementType="CALLABLE"><![CDATA[ {call JCG_TEST(#{IN_STR,mode=IN,jdbcType=VARCHAR},#{OUT_STR,mode=OUT,jdbcType=VARCHAR})} ]]> </select> View Code

 

2 存储过程参数为DATE

基于第1点的配置，service层与dao层不需要改动，改动controller、实体类、mapper

主要注意的是：存储过程输入参数输出参数为DATE格式时，mapper定义jdbcType为DATE，实体类要用Timestamp格式定义属性，否则时分秒会变成00:00:00。

输出得到时间戳后，再用new SimpleDateFormat("yyyy-MM-dd HH:mm:ss").format(entity.getM_GROUP_END())转成字符串格式的时间。

2-1 存储过程参数

M_DATETIME IN DATE, M_SEGMENT_BEGIN OUT DATE, M_SEGMENT_END OUT DATE, M_GROUP_BEGIN OUT DATE, M_GROUP_END OUT DATE, M_SEGMENT_NO OUT INTEGER, M_GROUP_CODE OUT VARCHAR2, RES OUT VARCHAR2 View Code

2-1 controller层

@RequestMapping("/GETPRO") @ResponseBody public PGetTimeSlotInfoEntity TESTPRO() throws SQLException {PGetTimeSlotInfoEntity entity = new PGetTimeSlotInfoEntity();SimpleDateFormat df = new SimpleDateFormat("yyyy-MM-dd HH:mm:ss");String time = df.format(new Date());Timestamp ts = Timestamp.valueOf(time);//获取当前时间的时间戳entity.setM_DATETIME(ts);//以时间戳给输入的DATE参数赋值 service.GetPro(entity);return entity; } View Code

2-2 实体类

public class PGetTimeSlotInfoEntity implements Serializable {private static final long serialVersionUID = -6556793741331167103L;private Timestamp M_DATETIME;private Timestamp M_SEGMENT_BEGIN;// 这里不用Date，应为传不了时分秒private Timestamp M_SEGMENT_END;private Timestamp M_GROUP_BEGIN;private Timestamp M_GROUP_END;private String M_SEGMENT_NO;private String M_GROUP_CODE;private String RES;public Timestamp getM_DATETIME() {return M_DATETIME;}public void setM_DATETIME(Timestamp m_DATETIME) {M_DATETIME = m_DATETIME;}public Date getM_SEGMENT_BEGIN() {return M_SEGMENT_BEGIN;}public void setM_SEGMENT_BEGIN(Timestamp m_SEGMENT_BEGIN) {M_SEGMENT_BEGIN = m_SEGMENT_BEGIN;}public Date getM_SEGMENT_END() {return M_SEGMENT_END;}public void setM_SEGMENT_END(Timestamp m_SEGMENT_END) {M_SEGMENT_END = m_SEGMENT_END;}public Timestamp getM_GROUP_BEGIN() {return M_GROUP_BEGIN;}public void setM_GROUP_BEGIN(Timestamp m_GROUP_BEGIN) {M_GROUP_BEGIN = m_GROUP_BEGIN;}public Timestamp getM_GROUP_END() {return M_GROUP_END;}public void setM_GROUP_END(Timestamp m_GROUP_END) {M_GROUP_END = m_GROUP_END;}public String getM_SEGMENT_NO() {return M_SEGMENT_NO;}public void setM_SEGMENT_NO(String m_SEGMENT_NO) {M_SEGMENT_NO = m_SEGMENT_NO;}public String getM_GROUP_CODE() {return M_GROUP_CODE;}public void setM_GROUP_CODE(String m_GROUP_CODE) {M_GROUP_CODE = m_GROUP_CODE;}public String getRES() {return RES;}public void setRES(String rES) {RES = rES;}} View Code

2-3 mapper

<select id="GetPro" parameterType="com.kh.zzkanban1.Entyties.PGetTimeSlotInfoEntity" useCache="false"statementType="CALLABLE"><![CDATA[ {call P_GET_TIME_SLOT_INFO(#{M_DATETIME,mode=IN,jdbcType=DATE},#{M_SEGMENT_BEGIN,mode=OUT,jdbcType=DATE},#{M_SEGMENT_END,mode=OUT,jdbcType=DATE},#{M_GROUP_BEGIN,mode=OUT,jdbcType=DATE},#{M_GROUP_END,mode=OUT,jdbcType=DATE},#{M_SEGMENT_NO,mode=OUT,jdbcType=INTEGER},#{M_GROUP_CODE,mode=OUT,jdbcType=VARCHAR},#{RES,mode=OUT,jdbcType=VARCHAR})}]]> </select> View Code
