问题 We have an Oracle stored procedure that returns its results in a SYS_REFCURSOR type OUT parameter. We would like to call this through a MyBatis mapper, the relevant part of the query string in the @Select annotation looks as follows @Select(value="call " + SCHEMA_NAME + "." + STORED_PROCEDURE_NAME + "(" + ... "#{" + P_RECORDSET_FIELD + ",javaType=java.sql.ResultSet,jdbcType=CURSOR,mode=OUT,resultMap=ownNameSpace.ownResultMap}," + ... where the resultMap property refers to the following XML

问题 I want to use Guava multimap as a resultMap with MyBatis, to return a resultset that has a collection of several one to many entries, but I am not able to figure out the exact syntax for the same. Below is a sample of my table : +----+---------+----------+-------------+ | ID | PART_ID | NAME | PART_FAMILY | +----+---------+----------+-------------+ | 1 | 1 | bush | 300 | | 2 | 1 | a-bush | 300 | | 3 | 1 | 300-bush | 300 | | 4 | 2 | nut | 301 | +----+---------+----------+-------------+ I want

问题 I'm aware that all spring steps need to have a reader, a writer, and optionally a processor. So even though my step only needs a writer, I am also fibbing a reader that does nothing but make spring happy. This is based on the solution found here. Is it outdated, or am I missing something? I have a spring batch job that has two chunked steps. My first step, deleteCount , is just deleting all rows from the table so that the second step has a clean slate. This means my first step doesn't need a

问题 Need to Integrate Camel and MyBatis with application using SpringBoot. SpringBoot provides out-of-box support for Camel and MyBatis. Also provides Camel and MyBatis SpringBoot starters. However, when i try to integrate Spring Boot application with Camel and MyBatis, it fails. I am using Java DSL based Camel Route. Also using Mybatis Spring boot dependencies.

问题 I need help with Spring Boot and MyBatis integration. I have an issue with custom BaseTypeHandler. I've created a mapper: @MappedTypes({LocalDateTime.class}) public class LocalDateTimeHandler extends BaseTypeHandler<LocalDateTime> { I've added a type handler: sqlSessionFactory.setTypeHandlers(new LocalDateTimeHandler[]{new LocalDateTimeHandler()}); And I have next error: org.apache.ibatis.executor.ExecutorException: No constructor found in com.some.space.SomeObject matching [java.lang.Integer

问题 The goal is to rollback all/any transactions in case of failure. But this doesn't work as expected. We use Spring MVC + JMS + Service + Mybatis. In the logs, the JMS is set to rollback, but the row is inserted and not rollback. Would like to know what I'm missing or doing wrong? The @Transactional tag was added recently. So not sure if it works as expected. Code: Service Class: @Transactional(value = "transactionManager", propagation = Propagation.REQUIRED, rollbackFor = Exception.class)

问题 Is there any way to get MyBatis to return an Optional<MyClass> instance rather than simply a MyClass instance? 回答1: Mybatis pre 3.5.0 Create custom ObjectFactory like this: class OptionalAwareObjectFactory extends DefaultObjectFactory { public Object create(Class type, List<Class> constructorArgTypes, List<Object> constructorArgs) { if (Optional.class.isAssignableFrom(type)) { return Optional.fromNullable(Iterables.getOnlyElement(constructorArgs)); } else { return super.create(type,

问题 I've been using Spring with MyBatis and it's been working really well for a single database. I ran into difficulties when trying to add another database (see reproducible example on Github). I'm using Spring Java configuration (i.e. not XML). Most of the examples I've seen show how to achieve this using XML. I have two data configuration classes (A & B) like this: @Configuration @MapperScan("io.woolford.database.mapper") public class DataConfigDatabaseA { @Bean(name="dataSourceA") public

问题 I'm referring to this article, in which we can use the AbstractRoutingDataSource from Spring Framework to dynamically change the data source used by the application. I'm using Mybatis (3.3.0) with Spring (4.1.6.RELEASE). I want to switch to the backup database if exception occurs while getting data from main db. In this example, i have used hsql and mysql db. RoutingDataSource : public class RoutingDataSource extends AbstractRoutingDataSource { @Override protected Object
