【问题描述】:
我尝试运行 this example,但不使用 Redis,而是使用本地 MySQL 服务器。
我已经像这样编辑了这个 Spring Boot 应用程序:
Gradle:
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 {
}
应用程序在 tomcat 上启动,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
我不记得读过有关手动创建此表的任何内容,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执行此操作。
【问题讨论】:

我认为您必须手动创建它们。例如,这里的文档有一个脚本来设置它正在使用的嵌入式数据库中的表:docs.spring.io/spring-session/docs/current/reference/html5/…
