org.apache.ibatis.builder.IncompleteElementException: Could not find parameter map
上周和同事一块开发一个功能模块，在开发中拉下来同事代码，在测试的时候，突然跑不通了，报错信息如下： org.apache.ibatis.builder.IncompleteElementException: Could not find parameter map java.util.Map at org.apache.ibatis.builder.MapperBuilderAssistant.getStatementParameterMap(MapperBuilderAssistant.java:320) at org.apache.ibatis.builder.MapperBuilderAssistant.addMappedStatement(MapperBuilderAssistant.java:296) at org.apache.ibatis.builder.xml.XMLStatementBuilder.parseStatementNode(XMLStatementBuilder.java:109) at org.apache.ibatis.session.Configuration.buildAllStatements(Configuration.java:753) at org.apache.ibatis.session.Configuration.hasStatement(Configuration.java:723) at org.apache.ibatis.session.Configuration.hasStatement(Configuration.java:718) at org.apache.ibatis.binding.MapperMethod$SqlCommand.<init>(MapperMethod.java:201) at org.apache.ibatis.binding.MapperMethod.<init>(MapperMethod.java:48) at org.apache.ibatis.binding.MapperProxy.cachedMapperMethod(MapperProxy.java:59) at org.apache.ibatis.binding.MapperProxy.invoke(MapperProxy.java:52) at com.sun.proxy.$Proxy40.insertSelective(Unknown Source) at com.weidai.urge.service.disposition.BidDispositionOrderServiceTest.testInsertSelective(BidDispositionOrderServiceTest.java:48) at sun.reflect.NativeMethodAccessorImpl.invoke0(Native Method) at sun.reflect.NativeMethodAccessorImpl.invoke(NativeMethodAccessorImpl.java:57) at sun.reflect.DelegatingMethodAccessorImpl.invoke(DelegatingMethodAccessorImpl.java:43) at java.lang.reflect.Method.invoke(Method.java:606) at org.junit.runners.model.FrameworkMethod$1.runReflectiveCall(FrameworkMethod.java:50) at org.junit.internal.runners.model.ReflectiveCallable.run(ReflectiveCallable.java:12) at org.junit.runners.model.FrameworkMethod.invokeExplosively(FrameworkMethod.java:47) at org.junit.internal.runners.statements.InvokeMethod.evaluate(InvokeMethod.java:17) at org.springframework.test.context.junit4.statements.RunBeforeTestMethodCallbacks.evaluate(RunBeforeTestMethodCallbacks.java:75) at org.springframework.test.context.junit4.statements.RunAfterTestMethodCallbacks.evaluate(RunAfterTestMethodCallbacks.java:86) at org.springframework.test.context.junit4.statements.SpringRepeat.evaluate(SpringRepeat.java:84) at org.junit.runners.ParentRunner.runLeaf(ParentRunner.java:325) at org.springframework.test.context.junit4.SpringJUnit4ClassRunner.runChild(SpringJUnit4ClassRunner.java:254) at org.springframework.test.context.junit4.SpringJUnit4ClassRunner.runChild(SpringJUnit4ClassRunner.java:89) at org.junit.runners.ParentRunner$3.run(ParentRunner.java:290) at org.junit.runners.ParentRunner$1.schedule(ParentRunner.java:71) at org.junit.runners.ParentRunner.runChildren(ParentRunner.java:288) at org.junit.runners.ParentRunner.access$000(ParentRunner.java:58) at org.junit.runners.ParentRunner$2.evaluate(ParentRunner.java:268) at org.springframework.test.context.junit4.statements.RunBeforeTestClassCallbacks.evaluate(RunBeforeTestClassCallbacks.java:61) at org.springframework.test.context.junit4.statements.RunAfterTestClassCallbacks.evaluate(RunAfterTestClassCallbacks.java:70) at org.junit.runners.ParentRunner.run(ParentRunner.java:363) at org.springframework.test.context.junit4.SpringJUnit4ClassRunner.run(SpringJUnit4ClassRunner.java:193) at org.junit.runner.JUnitCore.run(JUnitCore.java:137) at com.intellij.junit4.JUnit4IdeaTestRunner.startRunnerWithArgs(JUnit4IdeaTestRunner.java:68) at com.intellij.rt.execution.junit.IdeaTestRunner$Repeater.startRunnerWithArgs(IdeaTestRunner.java:51) at com.intellij.rt.execution.junit.JUnitStarter.prepareStreamsAndStart(JUnitStarter.java:237) at com.intellij.rt.execution.junit.JUnitStarter.main(JUnitStarter.java:70) Caused by: java.lang.IllegalArgumentException: Parameter Maps collection does not contain value for java.util.Map at org.apache.ibatis.session.Configuration$StrictMap.get(Configuration.java:853) at org.apache.ibatis.session.Configuration.getParameterMap(Configuration.java:625) at org.apache.ibatis.builder.MapperBuilderAssistant.getStatementParameterMap(MapperBuilderAssistant.java:318) … 39 more 看报错信息，也就是自己跑一个 junit test，测试批量插入，突然他就不行了，再看看自己写的批量插入没问题啊，我也没用 map，感觉好奇怪，就网上搜了一下这个问题，原来确实有问题，也确实在这个配置文件中，提示的错误也对，就是提示的位置不对。mybatis 中只要有任何一个地方报错，都无法通过。最后搜了一下发现是刚刚来下来的代码，同事新增了一个方法上将 parameterType 写成了 parameterMap 了 ...
