没有针对模式验证 JSON 对象的内置支持，因此您必须执行一些脚本，如Validate JSON against Schema in Java 文章中所述。万一引用的链接失效，您将需要JMeter Classpath中的以下库
activation-1.1.jar
btf-1.2.jar
guava-16.0.1.jar
jackson-annotations-2.2.3.jar
jackson-core-2.2.3.jar
jackson-coreutils-1.8.jar
jackson-databind-2.2.3.jar
joda-time-2.3.jar
jopt-simple-4.6.jar
json-schema-core-1.2.5.jar
json-schema-validator-2.2.6.jar
jsr305-3.0.0.jar
libphonenumber-6.2.jar
mailapi-1.4.3.jar
msg-simple-1.1.jar
rhino-1.7R4.jar
uri-template-0.9.jar
获取它们的最快和最简单的方法是创建最小的pom.xml 文件，例如：
<?xml version="1.0" encoding="UTF-8"?>
<project xmlns="http://maven.apache.org/POM/4.0.0"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/xsd/maven-4.0.0.xsd">
<modelVersion>4.0.0</modelVersion>
<groupId>foo</groupId>
<artifactId>bar</artifactId>
<version>1.0-SNAPSHOT</version>
<dependencies>
<!-- https://mvnrepository.com/artifact/com.github.fge/json-schema-validator -->
<dependency>
<groupId>com.github.fge</groupId>
<artifactId>json-schema-validator</artifactId>
<version>2.2.6</version>
</dependency>
<!-- https://mvnrepository.com/artifact/com.github.fge/jackson-coreutils -->
<dependency>
<groupId>com.github.fge</groupId>
<artifactId>jackson-coreutils</artifactId>
<version>1.8</version>
</dependency>
<!-- https://mvnrepository.com/artifact/com.github.fge/json-schema-core -->
<dependency>
<groupId>com.github.fge</groupId>
<artifactId>json-schema-core</artifactId>
<version>1.2.5</version>
</dependency>
</dependencies>
</project>
并执行mvn dependency:copy-dependencies 命令。
之后你就可以使用类似的东西了：
