Question

我是Spring Batch的新手，并使用通过使用Spring Tool Suite导入入门内容提供的批处理示例开始使用Spring Batch Application。我已经使用了该批处理示例并修改了类以触发我的批处理。修改批处理后，作业不会被触发。我已经包含了我修改过的java文件。我正在使用Oracle数据库连接和使用一些自定义类。使用Spring Boot我的输出中没有错误。为什么importCheckData（）或reader没有被触发？我在下面列出了我的课程： -

感谢您提前帮助！

CheckPrintApplication.java

import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
@SpringBootApplication
public class CheckPrintApplication {
 public static void main(String[] args) throws Exception {
    SpringApplication.run(CheckPrintApplication.class, args);
    }
}

这是我的 CheckPrintBatchConfiguration.java 文件

                .processor(processor()).writer(writer()).build();
    }
    // end::jobstep[]

    @Bean
    public JdbcTemplate jdbcTemplate(DataSource dataSource) {
        return new JdbcTemplate(dataSource);
    }

}

这是我的属性文件，用于连接oracle

#Oracle connection
spring.datasource.driver-class-name=oracle.jdbc.driver.OracleDriver
spring.jpa.database-platform=org.hibernate.dialect.Oracle12gDialect
spring.datasource.url= jdbc:oracle:thin:@//www.abc.com:1526/XXXXXX
spring.datasource.username=system
spring.datasource.password=user
spring.datasource.driver-class-name=oracle.jdbc.OracleDriver

oracle.username=system
oracle.password=user
oracle.url=jdbc:oracle:thin:@//www.abc.com:1526:1526/XXXXXX

这是我的简单POJO

package com.abc.canis.checkprint.data;   
public class PayslipRecord {

    private String mCheckNumber;
    private String mReceiverName;
    private String mCheckAmount;


    public PayslipRecord(String mCheckNumber, String mReceiverName, String mCheckAmount) {
        super();
        this.mCheckNumber = mCheckNumber;
        this.mReceiverName = mReceiverName;
        this.mCheckAmount = mCheckAmount;
    }

    public String getmCheckNumber() {
        return mCheckNumber;
    }
    public void setmCheckNumber(String mCheckNumber) {
        this.mCheckNumber = mCheckNumber;
    }
    public String getmReceiverName() {
        return mReceiverName;
    }
    public void setmReceiverName(String mReceiverName) {
        this.mReceiverName = mReceiverName;
    }
    public String getmCheckAmount() {
        return mCheckAmount;
    }
    public void setmCheckAmount(String mCheckAmount) {
        this.mCheckAmount = mCheckAmount;
    }



}

您的连接属性文件包含重复配置。以下配置应足以正确加载数据源。

spring.datasource.url=jdbc:oracle:thin:@//www.abc.com:1526/XXXXXX
spring.datasource.username=system
spring.datasource.password=user
spring.datasource.driver-class-name=oracle.jdbc.OracleDriver

此外，您在代码中不使用@Entity或任何其他CRUD操作，因此对于此示例，您不需要JPA配置。

但是，我最好的猜测是你的CheckPrintBatchConfiguration.java没有被加载到applicationcontext中。

使用@Import(CheckPrintBatchConfiguration.class)或use the recommended hierarchy上方的CheckPrintApplication.java。

使用Spring Boot的Spring Batch不运行批处理。你能帮我解决一下我的配置问题吗？
