我尝试运行this example但不使用Redis,而是使用我的本地MysqL服务器.

我编辑了这个春季启动应用程序,如下所示：

摇篮：

buildscript {
    repositories {
        mavenCentral()
    }
    dependencies {
        classpath("org.springframework.boot:spring-boot-gradle-plugin:$springBootVersion")
    }
}

apply plugin: 'spring-boot'

apply from: JAVA_GRADLE


//this 'if' statement is because I was getting error: Execution Failed for task ':samples:findbyusername:findMainClass'.
//> Could not find property 'main' on task ':samples:findbyusername:run'.
if (!hasProperty('mainClass')) {
    ext.mainClass = 'sample.FindByUsernameApplication'
}

tasks.findByPath("artifactoryPublish")?.enabled = false

group = 'samples'

dependencies {
    compile("org.springframework.boot:spring-boot-starter-jdbc:$springBootVersion") 
    compile group: 'MysqL',name: 'MysqL-connector-java',version: '6.0.2'
    compile group: 'org.springframework.session',name: 'spring-session',version: '1.2.0.RELEASE'



    compile project(':spring-session'),"org.springframework.boot:spring-boot-starter-web","org.springframework.boot:spring-boot-starter-thymeleaf","nz.net.ultraq.thymeleaf:thymeleaf-layout-dialect","org.springframework.security:spring-security-web:$springSecurityVersion","org.springframework.security:spring-security-config:$springSecurityVersion","com.maxmind.geoip2:geoip2:2.3.1","org.apache.httpcomponents:httpclient"

    testCompile "org.springframework.boot:spring-boot-starter-test","org.assertj:assertj-core:$assertjVersion"

    integrationTestCompile gebDependencies,"org.spockframework:spock-spring:$spockVersion"

}



def reservePort() {
    def socket = new ServerSocket(0)
    def result = socket.localPort
    socket.close()
    result
}

application.properties

spring.datasource.url = jdbc:MysqL://localhost:3306/TEST?characterEncoding=UTF-8&useUnicode=true&useJDBCCompliantTimezoneShift=true&useLegacyDatetimeCode=false&serverTimezone=UTC
spring.datasource.driverClassName = com.MysqL.jdbc.Driver
spring.datasource.username=root
spring.datasource.password=but

spring.thymeleaf.cache=false
spring.template.cache=false

HttpSessionConfig.java

@EnableJdbcHttpSession // <1>
public class HttpSessionConfig {
}

应用程序从tomcat开始,但是当我在浏览器中点击localhost时,我得到：

Whitelabel Error Page

This application has no explicit mapping for /error,so you are seeing this as a fallback.

There was an unexpected error (type=Internal Server Error,status=500).
PreparedStatementCallback; bad sql grammar [INSERT INTO SPRING_SESSION(SESSION_ID,CREATION_TIME,LAST_ACCESS_TIME,MAX_INACTIVE_INTERVAL,PRINCIPAL_NAME) VALUES (?,?,?)]; nested exception is java.sql.sqlSyntaxErrorException: Table 'test.spring_session' doesn't exist

我不记得读过关于手动创建这个表的任何内容所以我认为spring会为我处理它…

编辑：
我实际上尝试了manually create tables,然后应用程序运行正常.但我想我不应该手动这样做.
