我升级到Spring Boot 2.0.1.RELEASE，使用Spring数据JPA和Eclipselink作为我的提供者和Liquibase。我尝试启动服务器时遇到以下错误：

我的JPA配置类如下所示：
@Configuration
@EnableJpaRepositories("com.example.my.classes")
@EntityScan({"com.example.entities"})
public class JPASpringConfiguration extends JpaBaseConfiguration {
private String targetDatabase;
private final String sqlLoggingLevel;
@Autowired
public JPASpringConfiguration(
@Value("${spring.datasource.target-database}") String targetDatabase,
@Value("${eclipselink.logging.level.sql:INFO}") String sqlLoggingLevel,
DataSource dataSource,
JpaProperties jpaProperties,
ObjectProvider<JtaTransactionManager> transactionManagerObjectProvider,
ObjectProvider<TransactionManagerCustomizers> transactionManagerCustomizers) {
super(dataSource, jpaProperties, transactionManagerObjectProvider, transactionManagerCustomizers);
this.targetDatabase = targetDatabase;
this.sqlLoggingLevel = sqlLoggingLevel;
}
@Override
protected AbstractJpaVendorAdapter createJpaVendorAdapter() {
return new EclipseLinkJpaVendorAdapter();
}
@Override
protected Map<String, Object> getVendorProperties() {
HashMap<String, Object> map = new HashMap<>();
map.put("eclipselink.weaving", "false");
map.put("eclipselink.target-database", targetDatabase);
map.put("eclipselink.logging.level.sql", sqlLoggingLevel);
map.put("eclipselink.cache.shared.default", "false");
map.put(PersistenceUnitProperties.SESSION_CUSTOMIZER, IDSequenceRegistrar.class.getName());
return map;
}
@Bean
public SpringLiquibase liquibase(DataSource dataSource) {
SpringLiquibase springLiquibase = new SpringLiquibase() {
@Override
public void afterPropertiesSet() throws LiquibaseException {
configureLiquibase();
Liquibase liquibase = null;
try (Connection versionConnection = dataSource.getConnection()) {
versionConnection.setAutoCommit(true);
liquibase = createLiquibase(dataSource.getConnection());
String version = getDbVersion(versionConnection);
String previous = null;
while (!Objects.equals(version, previous)) {
setContexts(version);
performUpdate(liquibase);
previous = version;
version = getDbVersion(versionConnection);
}
} catch (SQLException e) {
throw new RuntimeException(e);
} finally {
if (liquibase != null && liquibase.getDatabase() != null) {
liquibase.getDatabase().close();
}
}
}
};
springLiquibase.setDataSource(dataSource);
springLiquibase.setChangeLog("classpath:/upgrade/db-changelog.xml");
return springLiquibase;
}
private String getDbVersion(Connection connection) throws SQLException {
String sql = "select tag from databasechangelog where tag is not null order by dateexecuted desc";
try (Statement statement = connection.createStatement();
ResultSet rs = statement.executeQuery(sql)) {
if (rs.next()) {
return rs.getString(1);
}
return "initial";
} catch (SQLException e) {
try (ResultSet rs = connection.getMetaData().getTables(null, null, "databasechangelog", null)) {
if (rs.next()) {
throw e;
} else {
return "initial";
}
}
}
}
private void configureLiquibase() {
ChangeFactory.getInstance().register(ChangeSetAwareCustomChangeWrapper.class);
}
}
在我的application.properties中，我定义了：
spring.datasource.target-database=PostgreSQL
spring.datasource.driver-class-name=org.postgresql.Driver
spring.datasource.url=jdbc:postgresql://localhost:5432/mydatabase
spring.datasource.username=myuser
spring.datasource.password=mypassword
spring.datasource.max-active=20
spring.datasource.max-idle=4
spring.datasource.max-wait=60000
spring.datasource.min-idle=2
spring.datasource.test-on-borrow=true
spring.datasource.test-on-return=true
spring.datasource.time-between-eviction-runs-millis=120000
spring.datasource.validation-query=select 1
这在以前的Spring Boot 1.3.5中工作（在Spring Boot 2中的HikariCP开关之前）。 JPASpringConfiguration以前能够在没有附加参数的情况下调用super（）。
当我在SimpleInstantiationStrategy中放置断点时，我可以看到传递的args为null。
到目前为止，我已尝试过：
感谢任何可以提供帮助的人！
答案 0 :(得分：1)
我可以将 springboot 与 hikari 一起使用。我没看到下课。你可以添加和检查吗？
@Configuration
@ConfigurationProperties(prefix = "spring.datasource.hikari")
public class CustomHikariConfig extends HikariConfig {
@Bean
public DataSource dataSource() {
return new HikariDataSource(this);
}
}
虽然您已经提到过使用了 spring.datasource.hikari。* ，但您可以再次使用下面提到的属性重新检查（如果您错过了任何一个）
###
# HikariCP Properties
###
spring.datasource.hikari.connection-timeout=60000
spring.datasource.hikari.maximum-pool-size=200
spring.datasource.hikari.minimum-idle=30
spring.datasource.hikari.idle-timeout=3000
spring.datasource.hikari.poolName=HikariCP
spring.datasource.type=com.zaxxer.hikari.HikariDataSource
spring.datasource.hikari.jdbcUrl=**data source url**
spring.datasource.hikari.username=**username**
spring.datasource.hikari.password=**password**
spring.datasource.hikari.driverClassName=com.mysql.jdbc.Driver
