例外：必须从Java代理开始才能使用InstrumentationLoadTimeWeaver。 请参阅Spring文档
我试图执行测试时遇到exception请帮忙。 先感谢您
我正在使用 ：
Java 7，EclipseLink 2.5.0-SNAPSHOT，Spring 3.2.4
测试配置文件 ：
exception跟踪 ：

如例外，请检查文档并尝试使用“-javaagent”运行测试，例如：
-javaagent:C:\Users\whatever\.m2\repository\org\springframework\spring-instrument\3.2.5.RELEASE\spring-instrument-3.2.5.RELEASE.jar
这对我有用：
spring-boot 1.5.3.RELEASE spring-data 1.5.3.RELEASE org.eclipse.persistence.jpa 2.6.4
在配置类中添加：
@Configuration @EnableLoadTimeWeaving(aspectjWeaving = EnableLoadTimeWeaving.AspectJWeaving.ENABLED) @Bean public InstrumentationLoadTimeWeaver loadTimeWeaver() throws Throwable { InstrumentationLoadTimeWeaver loadTimeWeaver = new InstrumentationLoadTimeWeaver(); return loadTimeWeaver; }
将属性文件设置为：
eclipselink.weaving=false
并通过以下方式将Vm参数设置为本地服务器
-javaagent:\org\springframework\spring-instrument\4.3.9.RELEASE\spring-instrument-4.3.9.RELEASE.jar
我有类似的问题。 我的解决方案是在tomcat conf目录的context.xml中添加一行。

如果您正在运行maven like build，请在您的surefire插件中包含一个额外的配置，如此片段中所示（不要忘记在您的pom.xml中包含$ {spring-version}属性）：
org.apache.maven.plugins maven-surefire-plugin 2.21.0 once -javaagent:"${settings.localRepository}/org/springframework/spring-instrument/${spring.version}/spring-instrument-${spring.version}.jar"
这个答案的细节。
