web3jをspring-mvcで立ち上げようとしたらこんなのでた
Etherum Web3j coreを使おうとして spring-boot と spring-mvcをうまく混在させたくて
設定してましたが以下のようなエラーが出てました

初期化クラスのWebInitializerを@SpringBootApplicationとして設定すると以下のようなエラーになり

これをsl4jが依存複数しているみたいなので、web3jの設定から産sy等しているsprinbgootを外します。
org.web3j
web3j-spring-boot-starter
1.6.0
org.springframework.boot
spring-boot-starter-logging
そこからSpring-MVCの設定クラス*1と初期化クラス*2を以下を参考に書き換えます
書き換えると行っても、Annotationを記載するのと継承クラスを変えただけ。
https://docs.spring.io/spring/docs/current/spring-framework-reference/web.html
- WebMvcConfigurer
@Configuration
@EnableWebMvc
public class ShareBaseWebConfig implements WebMvcConfigurer
- WebInitializer
public class WebInitializer implements WebApplicationInitializer {
とりあえず起動しました。
他のところでエラーになるかもしれないですが一旦ここまで
