背景：整理开发过程中的异常问题

java.lang.Exception: No tests found matching

一般出现在新导入的工程中。在sts中通过open project的方式导入工程后，运行test用例，报No tests found matching错误。

根因是build path问题。解决方案：

1 查看jdk版本，更新到目前的版本

2 删除项目中的junit包，右键 Build Path, addLibraay, 添加Junit4，在build path中通过add library的方式添加junit

java.lang.Exception: No tests found matching [{ExactMatcher:fDisplayName=testMessageProducer], {ExactMatcher:fDisplayName=testMessageProducer(com.jdjr.fmq.demo.ProducerTest)], {LeadingIdentifierMatcher:fClassName=com.jdjr.fmq.demo.ProducerTest,fLeadingIdentifier=testMessageProducer]] from org.junit.internal.requests.ClassRequest@27973e9bat org.junit.internal.requests.FilterRequest.getRunner(FilterRequest.java:35)at org.eclipse.jdt.internal.junit4.runner.JUnit4TestLoader.createFilteredTest(JUnit4TestLoader.java:83)at org.eclipse.jdt.internal.junit4.runner.JUnit4TestLoader.createTest(JUnit4TestLoader.java:74)at org.eclipse.jdt.internal.junit4.runner.JUnit4TestLoader.loadTests(JUnit4TestLoader.java:49)at org.eclipse.jdt.internal.junit.runner.RemoteTestRunner.runTests(RemoteTestRunner.java:525)at org.eclipse.jdt.internal.junit.runner.RemoteTestRunner.runTests(RemoteTestRunner.java:763)at org.eclipse.jdt.internal.junit.runner.RemoteTestRunner.run(RemoteTestRunner.java:463)at org.eclipse.jdt.internal.junit.runner.RemoteTestRunner.main(RemoteTestRunner.java:209)

java.lang.NoSuchMethodError: org.springframework.util.ClassUtils.determineCommonAncestor

这种错误一般是jar包冲突导致的。

解决办法：根据异常查找冲突的jar包，然后点击pom文件——Dependency Hierarchy 查找相关的jar包，会看到omitted for conflict with的相关信息。在导入的jar包中exclude即可。

jar包冲突导致的，排查下jar包。

org.xml.sax.SAXParseException: SchemaLocation: schemaLocation 值 '

org.xml.sax.SAXParseException: SchemaLocation: schemaLocation 值 '      http://www.springframework.org/schema/jdbc <br>http://www.springframework.org/schema/jdbc/spring-jdbc.xsd  <br><br>http://www.springframework.org/schema/aop ' 必须具有偶数个 URI。

原因：命名空间url对没有成对出现

xsi:schemaLocation属性的值由多个URI引用对组成，两个URI之间以空白符分隔。第一个URI是名称空间的名字，第二个URI给出模式文档的位置，模式处理器将从这个位置读取模式文档，该模式文档的目标名称空间必须与第一个URI相匹配。

遇到这种错误，不必慌张，主要看Cause by后面的原因
Caused by: org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'shiroFilter' defined in class path resource [spring/spring-shiro.xml]: Cannot resolve reference to bean 'securityManager' while setting bean property 'securityManager'; nested exception is org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'securityManager' defined in class path resource [spring/spring-shiro.xml]: Cannot resolve reference to bean 'shiroCacheManager' while setting bean property 'cacheManager'; nested exception is org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'shiroCacheManager' defined in class path resource [spring/spring-shiro.xml]: Initialization of bean failed; nested exception is org.springframework.beans.FatalBeanException: Error initializing bean [shiroCacheManager]; nested exception is org.apache.shiro.cache.CacheException: org.apache.shiro.config.ConfigurationException: Unable to obtain input stream for cacheManagerConfigFile [classpath:/spring/ehcache.xml]

如上，标红的部分，提示找不到路径，原因是
classpath:/spring/ehcache.xml中多了一个根路径，去掉即可。
