I'm developing an application using MyBatis and I'm facing a real strange problem. This already happened a few days ago but by uncommenting the following property on the dao-context2.xml I was able to solve However, it came back and I'm not able to get past it, even if the line is commented or not. Basic info The DDL for that table is the following (Oracle flavour) CREATE TABLE "T_APPLICATION_STATUS" ( "STATUS" VARCHAR2(100) NOT NULL ENABLE, "DATA_UPDATE" TIMESTAMP (6) ) ; Which gets mapped to the following Java Bean public class ApplicationStatus { private String lockStatus; private Date dataUpdate; public String getLockStatus() { return lockStatus; } public void setLockStatus(String lockStatus) { this.lockStatus = lockStatus; } public Date getDataUpdate() { return dataUpdate; } public void setDataUpdate(Date dataUpdate) { this.dataUpdate = dataUpdate; } } Everything is mapped inside the ApplicationStatusMapper.xml, defined in the following way Which corresponds to the following Mapper Interface (Java flavour) public interface ApplicationStatusMapper { @Update("UPDATE T_APPLICATION_STATUS " + "SET " + " STATUS = #{lockStatus}, " + " DATA_UPDATE = SYSDATE ") public void updateStatus(ApplicationStatus applicationStatus); @Select("SELECT STATUS AS lockStatus, DATA_UPDATE as dataUpdate FROM T_APPLICATION_STATUS") public ApplicationStatus getApplicationStatus(); } All of this is mapped with this snippet in the dao-context2.xml And this is the mybatis-config.xml Pom Dependencies The problem When the user navigates to the application, the very first query that it launches explodes. Specifically, that very first query goes to check whether the application is in mainteneance or not. Caused by: java.lang.IllegalArgumentException: Result Maps collection does not contain value for some.package.db.mappers.DatiAperturaContoMapper.DatiAperturaContoEX In my project, I do have something related to DatiAperturaContoMapper and DatiAperturaContoEX, but they're no way related to the T_APPLICATION_STATUS mapper. The result is the following error, which gets fired when the ApplicationStatusMapper.java is called. I'm also not able to setup, sadly, any kind of logging for MyBatis. Things I tried Some googling suggested me the following troubleshooting, which did not work: SQL syntax on the T_APPLICATION_STATUS (Though everything seems fine) mapperLocations that points to load everything (This seemed to work, though now on deploy it takes forever to load and brings to an OOM error) I'm looking for any suggestion that could point me in the right direction. Does anybody know where I could start? 1.java.lang.IllegalArgumentException: Result Maps collection does not contain value for com.model.User Solution: 1. When there is The attributes in the Solution: 2. Change resultMap to resultType = "com.lanstech.platform.model.User" This will cause some problems: similar to many data returned is null. This is because the return value matches com.lanstech.platform.model.User and the returned attributes are the field names of the database. When the field names of the database and the attribute names in User are different, the data cannot be matched. So when using this method, the data and the attribute name must be the same. 今天做springmvc+mybatis+spring的项目的时候发现了一个异常。如下： org.apache.ibatis.builder.IncompleteElementException: Could not find result map java.lang.Integer at org.apache.ibatis.builder.MapperBuilderAssistant.setStatementResultMap(MapperBuilderAssistant.java: 346 ) at org.apache.ibatis.builder.MapperBuilderAssistant.addMappedStatement(MapperBuilderAssistant.java: 284 ) at org.apache.ibatis.builder.xml.XMLStatementBuilder.parseStatementNode(XMLStatementBuilder.java: 107 ) at org.apache.ibatis.session.Configuration.buildAllStatements(Configuration.java: 698 ) at org.apache.ibatis.session.Configuration.hasStatement(Configuration.java: 668 ) at org.apache.ibatis.session.Configuration.hasStatement(Configuration.java: 663 ) at org.apache.ibatis.binding.MapperMethod$SqlCommand.
