如果要为WireMock以外的存根服务器生成存根，则可以插入自己的StubGenerator接口实现。以下代码清单显示了StubGenerator接口：

package org.springframework.cloud.contract.verifier.converter

import groovy.transform.CompileStatic

import org.springframework.cloud.contract.spec.Contract
import org.springframework.cloud.contract.verifier.file.ContractMetadata

/**
 * Converts contracts into their stub representation.
 *
 * @since 1.1.0
 */
@CompileStatic
interface StubGenerator {

	/**
	 * @return {@code true} if the converter can handle the file to convert it into a stub.
	 */
	boolean canHandleFileName(String fileName)

	/**
	 * @return the collection of converted contracts into stubs. One contract can
	 * result in multiple stubs.
	 */
	Map<Contract, String> convertContents(String rootName, ContractMetadata content)

	/**
	 * @return the name of the converted stub file. If you have multiple contracts
	 * in a single file then a prefix will be added to the generated file. If you
	 * provide the {@link Contract#name} field then that field will override the
	 * generated file name.
	 *
	 * Example: name of file with 2 contracts is {@code foo.groovy}, it will be
	 * converted by the implementation to {@code foo.json}. The recursive file
	 * converter will create two files {@code 0_foo.json} and {@code 1_foo.json}
	 */
	String generateOutputFileNameForInput(String inputFileName)
}

同样，您必须提供一个spring.factories文件，例如以下示例中所示的文件：

# Stub converters
org.springframework.cloud.contract.verifier.converter.StubGenerator=\
org.springframework.cloud.contract.verifier.wiremock.DslToWireMockClientConverter

默认实现是WireMock存根生成。

您可以提供多个存根生成器实现。例如，从单个DSL，您可以同时生成WireMock存根和Pact文件。
