在主要方法中它起作用了，那么 springboot 有什么问题，我看过了，但没有解决任何问题，有没有人知道什么可能正在发生，依赖关系，spring 配置，休眠配置，pom.xml 配置，项目配置，任何东西？
我添加了 EntityScan，但错误仍然存在。
package br.com.api;
import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
import org.springframework.boot.autoconfigure.domain.EntityScan;
@SpringBootApplication
@EntityScan(basePackages = "br.com.api.entities")
public class ApiApplication {
public static void main(String[] args) {
SpringApplication.run(ApiApplication.class, args);
}
}
api 我正在使用：https://github.com/Eduardo-Karpinski/hcf
为了解决问题，我将代码修改为更接近 Spring 想要的模型，但错误仍然存在。
package br.com.api;
import org.springframework.boot.autoconfigure.domain.EntityScan;
import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;
import br.com.hcf.HCFFactory;
@Configuration
@EntityScan(basePackages = "br.com.api.entities")
public class Config {
@Bean
public HCFFactory factory() {
HCFFactory factory = HCFFactory.getInstance();
return factory;
}
}
package br.com.api.controls;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.http.HttpStatus;
import org.springframework.http.ResponseEntity;
import org.springframework.web.bind.annotation.GetMapping;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RestController;
import br.com.api.entities.Persona;
import br.com.hcf.HCFConnection;
import br.com.hcf.HCFFactory;
@RestController
@RequestMapping("api/v1/public")
public class CharacterControl {
@Autowired
HCFFactory factory;
@GetMapping("/characters")
public ResponseEntity<Object> getAll() {
try {
factory.getFactory();
factory.getAnnotatedClasses();
return ResponseEntity.ok(new HCFConnection<>(Persona.class).all());
} catch (Exception e) {
e.printStackTrace();
return ResponseEntity.status(HttpStatus.INTERNAL_SERVER_ERROR).body(e.getMessage());
}
}
}
在调试 MetamodelImpl class 期间，我发现出现在我面前的错误是不可能的，因为我想保留的 class 在 Map "** jpaEntityTypeMap **" 中。
调试中的变量值：
jpaEntityTypeMap ConcurrentHashMap <K, V> (id = 135)
[0] ConcurrentHashMap $ MapEntry <K, V> (id = 252)
key Class <T> (br.com.api.entities.Persona) (id = 156)
value EntityTypeImpl <J> (id = 157)
cls Class <T> (br.com.api.entities.Persona) (id = 244)
我开始认为这是一个 spring 引导错误
在运行进行其他测试时，我意识到当运行在CharacterControl class
中进行以下块时
public static void main(String[] args) {
HCFFactory.getInstance().getFactory();
HCFFactory.getInstance().getAnnotatedClasses();
new HCFConnection<>(Persona.class).all().forEach(System.out::println);
}
同样的错误是因为**jpaEntityTypeMap**为null，但是我在Personaclass上运行的时候没有报错，什么意思？
这次改了还是一样的错误，spring不喜欢我。

似乎未扫描包“br.com.api.entities”，因此您的实体未知。您应该添加：
@EntityScan(basePackages = "br.com.api.entities")
在配置中 class 所以它会被识别。
此致。
在解析您的代码时，我注意到您正在以静态方式创建自己的会话工厂和实体管理器。所以我认为你应该对实体包扫描做同样的事情，因为 @EntityScan 不会工作，因为你没有使用 spring.
您应该手动添加实体（或通过扫描包裹），例如：
Configuration conf = new Configuration();
...
conf.addAnnotatedClass(EntityClass.class)
我在一个项目中测试了你的控制器代码，它工作正常，我没有包括 spring-boot-starter-data-jpa 因为你想自己构建会话工厂:

在主要方法中它起作用了，那么 springboot 有什么问题，我看过了，但没有解决任何问题，有没有人知道什么可能正在发生，依赖关系，spring 配置，休眠配置，pom.xml 配置，项目配置，任何东西？
我添加了 EntityScan，但错误仍然存在。
package br.com.api;
import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
import org.springframework.boot.autoconfigure.domain.EntityScan;
@SpringBootApplication
@EntityScan(basePackages = "br.com.api.entities")
public class ApiApplication {
public static void main(String[] args) {
SpringApplication.run(ApiApplication.class, args);
}
}
api 我正在使用：https://github.com/Eduardo-Karpinski/hcf
为了解决问题，我将代码修改为更接近 Spring 想要的模型，但错误仍然存在。
package br.com.api;
import org.springframework.boot.autoconfigure.domain.EntityScan;
import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;
import br.com.hcf.HCFFactory;
@Configuration
@EntityScan(basePackages = "br.com.api.entities")
public class Config {
@Bean
public HCFFactory factory() {
HCFFactory factory = HCFFactory.getInstance();
return factory;
}
}
package br.com.api.controls;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.http.HttpStatus;
import org.springframework.http.ResponseEntity;
import org.springframework.web.bind.annotation.GetMapping;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RestController;
import br.com.api.entities.Persona;
import br.com.hcf.HCFConnection;
import br.com.hcf.HCFFactory;
@RestController
@RequestMapping("api/v1/public")
public class CharacterControl {
@Autowired
HCFFactory factory;
@GetMapping("/characters")
public ResponseEntity<Object> getAll() {
try {
factory.getFactory();
factory.getAnnotatedClasses();
return ResponseEntity.ok(new HCFConnection<>(Persona.class).all());
} catch (Exception e) {
e.printStackTrace();
return ResponseEntity.status(HttpStatus.INTERNAL_SERVER_ERROR).body(e.getMessage());
}
}
}
在调试 MetamodelImpl class 期间，我发现出现在我面前的错误是不可能的，因为我想保留的 class 在 Map "** jpaEntityTypeMap **" 中。
调试中的变量值：
jpaEntityTypeMap ConcurrentHashMap <K, V> (id = 135)
[0] ConcurrentHashMap $ MapEntry <K, V> (id = 252)
key Class <T> (br.com.api.entities.Persona) (id = 156)
value EntityTypeImpl <J> (id = 157)
cls Class <T> (br.com.api.entities.Persona) (id = 244)
我开始认为这是一个 spring 引导错误
在运行进行其他测试时，我意识到当运行在CharacterControl class
中进行以下块时public static void main(String[] args) {
HCFFactory.getInstance().getFactory();
HCFFactory.getInstance().getAnnotatedClasses();
new HCFConnection<>(Persona.class).all().forEach(System.out::println);
}
同样的错误是因为**jpaEntityTypeMap**为null，但是我在Personaclass上运行的时候没有报错，什么意思？
这次改了还是一样的错误，spring不喜欢我。

似乎未扫描包“br.com.api.entities”，因此您的实体未知。您应该添加：
@EntityScan(basePackages = "br.com.api.entities")
在配置中 class 所以它会被识别。
此致。
在解析您的代码时，我注意到您正在以静态方式创建自己的会话工厂和实体管理器。所以我认为你应该对实体包扫描做同样的事情，因为 @EntityScan 不会工作，因为你没有使用 spring.
您应该手动添加实体（或通过扫描包裹），例如：
Configuration conf = new Configuration();
...
conf.addAnnotatedClass(EntityClass.class)
我在一个项目中测试了你的控制器代码，它工作正常，我没有包括 spring-boot-starter-data-jpa 因为你想自己构建会话工厂:
