运行SpringMVC+SpringBootGradleJava9项目，并最终使用java。lang.NoClassDefFoundError:java/sql/SQLException

Question

我有一个非常简单的应用程序，可以完美地与Java1.8配合使用，它包含一个主类，比如

package com.company.getworks.start;


import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.EnableAutoConfiguration;
import org.springframework.context.annotation.ComponentScan;
import org.springframework.context.annotation.Configuration;

@Configuration
@ComponentScan()
@EnableAutoConfiguration
public class ApplicationMain {

    public static void main(String[] args) {
        SpringApplication.run(ApplicationMain.class, args);
    }

}

以及一个带有@RestContoller的类，该类只包含一个带有@RequestMapping("/hello")的方法

我添加了模块信息。看起来像

module com.company.getworks.start {
    requires spring.boot;
    requires spring.webmvc;
}

还有我的身材。格雷德尔是

group 'com.company'
version '1.0-SNAPSHOT'

apply plugin: 'java'

sourceCompatibility = 1.9

repositories {
    mavenCentral()
}

dependencies {
    final def springVersion='4.3.10.RELEASE'
    final def springBootVersion='1.5.6.RELEASE'
    testCompile group: 'junit', name: 'junit', version: '4.12'
    compile (group: 'org.springframework', name: 'spring-webmvc', version: springVersion) {
        exclude group: 'commons-logging', module: 'commons-logging'
    }
    compile(group: "org.springframework.boot", name: "spring-boot-starter-web", version: springBootVersion) {
        exclude group: 'commons-logging', module: 'commons-logging'
    }
}

ext.moduleName = 'com.company.getworks.start'

compileJava {
    inputs.property("moduleName", moduleName)
    doFirst {
        options.compilerArgs = [
            '--module-path', classpath.asPath,
            '--add-modules', 'spring.boot',
            '--add-modules', 'spring.webmvc',
    ]
    classpath = files()
    }
}

运行clean compileJava以构建成功结束，但当我试图运行我的ApplicationMain时。java它以Exception in thread "main" java.lang.IllegalArgumentException: Cannot instantiate interface org.springframework.context.ApplicationContextInitializer : org.springframework.boot.context.ConfigurationWarningsApplicationContextInitializer Caused by: java.lang.NoClassDefFoundError: java/sql/SQLException结尾 我做错了什么

Answer 1

我不得不

1）升级至spring boot 2

2）将我的依赖项列表更改为

dependencies {
    final def springVersion='4.3.10.RELEASE'
    final def springBootVersion='2.0.0.RELEASE'
    testCompile group: 'junit', name: 'junit', version: '4.12'
    compile (group: 'org.springframework', name: 'spring-webmvc', version: springVersion) {
        exclude group: 'commons-logging', module: 'commons-logging'
    }
    compile(group: "org.springframework.boot", name: "spring-boot-starter-web", version: springBootVersion) {
        exclude group: 'commons-logging', module: 'commons-logging'
        exclude group: 'javax.annotation', module: 'javax.annotation-api'
    }
}

3）更新模块信息。爪哇

module com.company.getworks.start {
    requires spring.boot;
    requires spring.webmvc;
    requires spring.context;
    requires spring.boot.autoconfigure;
    requires spring.web;
    opens com.company.getworks.start;
    exports com.company.getworks.web;
}

其中com.company.getworks.web是包含@RestController类的包

4）正如正确提到的@miroh add add modules java。sql到我的java命令
