Could you post your lvfi-dao.xml file? What are that asteriscs for?

> dbo.get_fxd_incm_currency_grid(#{currency_req,javaType=double,jdbcType=NUME RIC})}

[Detali]

Those Asteriscs are package name

here is the lvfi-dao.xml

<bean id="sqlSessionFactory"
class="org.mybatis.spring.SqlSessionFactoryBean">
<property name="dataSource" ref="DataSource" />
</bean>

<bean id="fixedIncomeMapper"
class="org.mybatis.spring.mapper.MapperFactoryBean">
<property name="mapperInterface"

ref="com.jpm.mybatis.model.FixedIncomeMapper" />

<property name="sqlSessionFactory" ref="sqlSessionFactory" />
</n>
</bean>
<bean id="fixedIncomeservice"

class="com.jpm.mybatis.dao.FixedIncomeServiceImpl">

[Eduardo]

This line:

<property name="mapperInterface"
ref="com.jpm.mybatis.model.FixedIncomeMapper" />

should be:
<property name="mapperInterface"
value="com.jpm.mybatis.model.FixedIncomeMapper" />

Thanks for quick reply , i have fixed that now it;s it throws error
like

Bean property 'fixedIncomeMapper' is not writable or has an invalid
setter method. Does the parameter type of the setter match the return
type of the getter?

<bean id="sqlSessionFactory"
class="org.mybatis.spring.SqlSessionFactoryBean">

<property name="dataSource" ref="creditDataSource" />
<property name="configLocation" value="classpath:mybatis/Mybatis-
Config.xml" />

</bean>

<bean id="fixedIncomeMapper"
class="org.mybatis.spring.mapper.MapperFactoryBean">
<property name="mapperInterface"

value="com.jpm.pb.crdit.mybatis.model.FixedIncomeMapper" />

<property name="sqlSessionFactory" ref="sqlSessionFactory" />

</bean>


<bean id="fixedIncomeDAO"
class="com.jpm.pb.crdit.mybatis.dao.FixedIncomeDAOImpl">

<property name="fixedIncomeMapper" ref="fixedIncomeMapper" />
</bean>

<!-- <bean id="fixedMapper"
class="org.mybatis.spring.mapper.MapperScannerConfigurer">
<property name="basePackage"
value="com.jpm.pb.crdit.mybatis.model" />
</bean> -->

[Eduardo]

I would say that your FixedIncomeDAOImpl misses a
setFixedIncomeMapper() method

[Detali]

Appreciate your help
correct, that is i figure it out fixed the code ,but some how not gets
the Mapper reference in fixedIncomeDAOImpl.it;s just throw null
pointer. i am using mybatis-spring-1.0.1-SNAPSHOT.jar and
mybatis-3.0.5-SNAPSHOT.jar

(return fixedIncomeMapper.getTimeToMaturiy() never works )


public class FixedIncomeDAOImpl implements FixedIncomeDAO {
protected Logger logger =
LoggerFactory.getLogger(FixedIncomeDAOImpl.class);

@Autowired
private FixedIncomeMapper fixedIncomeMapper;

public FixedIncomeMapper getFixedIncomeMapper() {
return fixedIncomeMapper;
}

public void setFixedIncomeMapper(FixedIncomeMapper fixedIncomeMapper)
{
this.fixedIncomeMapper = fixedIncomeMapper;
}

@SuppressWarnings("unchecked")
public List<CcyDenomination> getTimeToMaturiy(double req){
try {
return fixedIncomeMapper.getTimeToMaturiy();

} catch (Exception ex) {
logger.error("SQL error, while running - getccydenom ", ex);
}
return null;
}
}

lvfi-data.xml

<bean id="sqlSessionFactory"
class="org.mybatis.spring.SqlSessionFactoryBean">
<property name="dataSource" ref="creditDataSource" />
<property name="configLocation" value="classpath:mybatis/Mybatis-
Config.xml" />
</bean>

<bean id="fixedIncomeMapper"
class="org.mybatis.spring.mapper.MapperFactoryBean">
<property name="mapperInterface"

value="com.jpmorgan.pb.credit.mybatis.model.FixedIncomeMapper" />

<property name="sqlSessionFactory" ref="sqlSessionFactory" />
</bean>

<bean id="fixedIncomeDAO"

class="com.jpmorgan.pb.credit.mybatis.dao.FixedIncomeDAOImpl">

<property name="fixedIncomeMapper" ref="fixedIncomeMapper" />
</bean>

FixedIncomeMapper.java

public interface FixedIncomeMapper {
public List<CcyDenomination> getTimeToMaturiy();
}

FixedIncomeMapper.xml
<mapper
namespace="com.jpmorgan.pb.credit.mybatis.model.FixedIncomeMapper">
<resultMap id="ccydenomrs" resultType="ccydenom">
<result property="ccydenomination" column="Currency_denominated"/>
</resultMap>

<select id="getTimeToMaturiy" resultMap="ccydenomrs"
statementType="CALLABLE">
{call dbo.get_fxd_incm_currency_grid()}
</select>
</mapper>

Please post a stacktrace. That will help.

Is your autowiring set up properly? You should set the component scan element to the packages that have classes that need to be autowired. Use a debugger to see that fixedIncomeMapper is being autowired.
