Question

我正在使用Hikari CP和JDBC模板将Controller中的传入请求参数插入数据库。

所以我做了以下事情：

@RestController
public class HomeController  {

@Autowired
    private JdbcTemplate jtm;


@RequestMapping(value="/insert/data",produces={MediaType.APPLICATION_JSON_VALUE},method=RequestMethod.GET)
    public ResponseEntity<?> insertData(@RequestParam("id")int id ,@RequestParam("name")String name) throws IOException, ClassNotFoundException, SQLException{


           String sql = "INSERT INTO public.users(id, name) VALUES (?, ?, ?);";


            jtm.update(sql,id,name);


}
}

但是这会引发以下错误：

The type org.springframework.jdbc.support.KeyHolder cannot be resolved. It is indirectly referenced from required .class files

我在/ src / main / resources

中有一个hikari.properties

driverClassName=org.postgresql.Driver
jdbcUrl=jdbc:postgresql://10.1.9.72:5432/data_base
maximumPoolSize=20
username=user
password=password
dataSource.cachePrepStmts=true
dataSource.prepStmtCacheSize=250
dataSource.prepStmtCacheSqlLimit=2048

我的HikariCP配置Java类

AppConfig.java

import com.zaxxer.hikari.HikariConfig;
import com.zaxxer.hikari.HikariDataSource;
import java.sql.SQLException;
import javax.sql.DataSource;
import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;

@Configuration
public class AppConfig {

    @Bean(destroyMethod = "close")
    public DataSource dataSource() throws SQLException {
        HikariConfig config = new HikariConfig("/hikari.properties");
        HikariDataSource dataSource = new HikariDataSource(config);

        return dataSource;
    }
}

我在我的pom.xml中添加了以下依赖项（Hikari Cp，Spring JBDC，spring-tx）

 <dependency>
        <groupId>org.springframework.boot</groupId>
            <artifactId>spring-boot-starter-jdbc</artifactId>
    </dependency>


    <dependency>
        <groupId>com.zaxxer</groupId>
        <artifactId>HikariCP-java7</artifactId>
        <version>2.4.12</version>
    </dependency>
<dependency>
    <groupId>org.springframework</groupId>
    <artifactId>spring-tx</artifactId>
    <version>3.0.0.RELEASE</version>
</dependency>
<dependency>
    <groupId>org.springframework</groupId>
    <artifactId>spring-jdbc</artifactId>
    <version>3.2.1.RELEASE</version>
</dependency>

感谢任何帮助

org.springframework.jdbc.support.KeyHolder无法解析。它是从所需的.class文件间接引用的
