com.tuya.connector.api.exceptions.ConnectorDelegateException: Error create retrofit delegate for connector :

[rayxie2046]

我遇到这个问题，不知如何处理，可能是与项目框架包冲突？ com.tuya.connector.api.exceptions.ConnectorDelegateException: Error create retrofit delegate for connector : cn.ac.xxx.admin.connector.HomeConnector. Cause: javassist.bytecode.DuplicateMemberException: duplicate method: queryGroup in cn.ac.xxx.admin.connector.$HomeConnector

请问您项目中有引用 retrofit 的依赖吗，依赖的版本是多少。

[rayxie2046]

项目中没有用到 retrofit2， 我看了 retrofit2 在 tuya connector 依赖里面 [INFO] +- com.tuya:tuya-spring-boot-starter:jar:1.1.0:compile [INFO] | +- com.tuya:connector-spring-boot-starter:jar:1.1.0:compile [INFO] | | +- com.tuya:connector-spring-boot-autoconfigure:jar:1.1.0:compile [INFO] | | +- com.tuya:connector-spring:jar:1.1.0:compile [INFO] | | - com.tuya:connector-api:jar:1.1.0:compile [INFO] | | +- com.squareup.retrofit2:retrofit:jar:2.9.0:compile [INFO] | | +- com.squareup.okhttp3:logging-interceptor:jar:3.14.9:compile [INFO] | | - com.squareup.retrofit2:converter-gson:jar:2.9.0:compile [INFO] | +- com.tuya:tuya-api:jar:1.1.0:compile [INFO] | | +- com.tuya:tuya-common:jar:1.1.0:compile [INFO] | | +- ch.qos.logback:logback-classic:jar:1.2.3:compile [INFO] | | - ch.qos.logback:logback-core:jar:1.2.3:compile [INFO] | - com.tuya:tuya-messaging:jar:1.1.0:compile [INFO] | +- com.tuya:connector-messaging:jar:1.1.0:compile [INFO] | +- org.apache.pulsar:pulsar-client:jar:2.5.0:compile [INFO] | | +- org.apache.pulsar:pulsar-client-api:jar:2.5.0:compile [INFO] | | +- org.apache.pulsar:pulsar-transaction-common:jar:2.5.0:compile [INFO] | | +- com.google.protobuf:protobuf-java-util:jar:3.11.4:compile [INFO] | | +- org.apache.pulsar:protobuf-shaded:jar:2.1.0-incubating:compile [INFO] | | +- org.checkerframework:checker-qual:jar:2.0.0:compile [INFO] | | +- org.codehaus.mojo:animal-sniffer-annotations:jar:1.14:compile [INFO] | | +- org.lz4:lz4-java:jar:1.5.0:compile [INFO] | | +- com.github.luben:zstd-jni:jar:1.3.7-3:compile [INFO] | | +- org.bouncycastle:bcpkix-jdk15on:jar:1.60:compile [INFO] | | +- org.bouncycastle:bcprov-jdk15on:jar:1.60:compile [INFO] | | +- com.sun.activation:javax.activation:jar:1.2.0:compile [INFO] | | - javax.validation:validation-api:jar:2.0.1.Final:compile [INFO] | +- javax.annotation:javax.annotation-api:jar:1.3.2:compile [INFO] | - org.reflections:reflections:jar:0.9.10:compile

HomeConnector 是否定义了两个重复的方法：queryGroup() ?

[rayxie2046]

不会啊，我尝试修改了类名称和方法名，问题依然没有解决

[Zhang-BigSmart]

请问您使用的tuya-connector版本是多少

[rayxie2046]

com.tuya:tuya-spring-boot-starter:jar:1.1.0:

[rayxie2046]

    <dependency>
        <groupId>com.tuya</groupId>
        <artifactId>tuya-spring-boot-starter</artifactId>
        <version>1.1.0</version>
    </dependency>

[Zhang-BigSmart]

试一下使用1.1.3版本呢

[rayxie2046]

还是有同样的问题

可以贴一下NullPointerException具体的异常吗

[rayxie2046]

问题解决，少一个 注解 @Body @PUT("/v1.0/homes/{home_id}") TuyaResult update(@Path("home_id") Integer homeId, Map param);
