创建 bean Mvc 时出错 Mysql Hibernate Spring
Error creating bean Mvc Mysql Hibernate Spring
我尝试使用 spring 框架和 FreeMarker 创建 Maven progect。我还创建了一些实体和一个连接数据库和一个视图。我开始 Tomcat 查看结果，如果这个应用程序正在运行。而且我有一个错误，无法解决！当我 statrt Tomcat 我得到“HTTP 状态 500 – 内部服务器错误”。
这是一个配置Class
@EnableWebMvc
@Configuration
@ComponentScan(basePackages="Name.Controller")
@EnableJpaRepositories
@EnableTransactionManagement
//@PropretySource("classpath:database.propreties")
public class AppConfig {
@Bean
public FreeMarkerViewResolver configResoler() {
FreeMarkerViewResolver resolver= new FreeMarkerViewResolver();
resolver.setPrefix("");
resolver.setSuffix(".ftl");
resolver.setCache(true);
return resolver;
}
@Bean
public FreeMarkerConfigurer configurerFM() {
FreeMarkerConfigurer config= new FreeMarkerConfigurer();
config.setTemplateLoaderPath("/WEB-INF/view/");
return config;
}
@Bean
public DataSource getDataSource(){
DriverManagerDataSource db= new DriverManagerDataSource();
db.setUsername("root");
db.setPassword("root");
db.setDriverClassName("org.h2.Driver"); // was com.mysql.cj.jdbc.Driver"
db.setUrl("jdbc:mysql://localhost:3306/Java");
return db;
}
@Bean
public LocalContainerEntityManagerFactoryBean getEntityManagerFactory(){
HibernateJpaVendorAdapter adapter=new HibernateJpaVendorAdapter();
adapter.setDatabase(Database.MYSQL);
adapter.setGenerateDdl(true);
LocalContainerEntityManagerFactoryBean factory= new LocalContainerEntityManagerFactoryBean();
factory.setDataSource(getDataSource());
factory.setJpaVendorAdapter(adapter);
factory.setPackagesToScan(getClass().getPackage().getName());
return factory;
}
@Bean
public PlatformTransactionManager getTransactionManager(){
// JpaTransactionManager jtm= new JpaTransactionManager(getEntityManager().getObject());
return new JpaTransactionManager(getEntityManagerFactory().getObject());
}

在文件 pom 中，我有 2 个驱动程序，一个用于 MariaDB，一个用于 MySql。这只是因为我试图了解问题是否存在，但我使用的是 MySql 而不是 MariaDB
我该如何解决？谢谢

我在你的 maven 设置中看不到 h2 数据库依赖，添加这个：
<dependency>
<groupId>com.h2database</groupId>
<artifactId>h2</artifactId>
<version>1.4.200</version>
</dependency>
如果您想使用 MySQL，为什么您的数据源驱动程序 class 名称首先声明为 h2？将其更改为 com.mysql.cj.jdbc.Driver
db.setDriverClassName("com.mysql.cj.jdbc.Driver");
我尝试使用 spring 框架和 FreeMarker 创建 Maven progect。我还创建了一些实体和一个连接数据库和一个视图。我开始 Tomcat 查看结果，如果这个应用程序正在运行。而且我有一个错误，无法解决！当我 statrt Tomcat 我得到“HTTP 状态 500 – 内部服务器错误”。

我在你的 maven 设置中看不到 h2 数据库依赖，添加这个：
<dependency>
<groupId>com.h2database</groupId>
<artifactId>h2</artifactId>
<version>1.4.200</version>
</dependency>
如果您想使用 MySQL，为什么您的数据源驱动程序 class 名称首先声明为 h2？将其更改为 com.mysql.cj.jdbc.Driver
db.setDriverClassName("com.mysql.cj.jdbc.Driver");
