java使用POST方法Spring Boot中的JDBCTemplate存储对象数组

Question

如何使用JDBCTemplate将对象数组插入数据库？我有一个可变长度的对象数组，它来自我控制器中的POST方法

我看了这些,

和其他人一样，他们似乎不适合我的需要

控制器

// Service
@Autowired
private DBService tool;

@PostMapping(value = "/foo")
private void storeData(@RequestBody CustomObject[] customObjects) {
    // Calls service then DAO
    tool.storeData(customObjects);
}

POJO对象

public class CustomObject {

    private Integer id;
    private String name;

    // Getters & Setters for class attributes
    ...
}

道是这样吗？因为我想分别存储每个数组元素，每个元素都有自己的行

@Autowired
private JdbcTemplate temp;

public void storeData(CustomObject[] customObjects) {

    String sql = "INSERT INTO FooBar(name) VALUES(\'" + customObjects.toString() + "\');";

    temp.update(sql);
}

理想情况下，您希望迭代数组并保存每个“CustomObject”

private JdbcTemplate temp;

public void storeData(CustomObject customObject) {

    String sql = "INSERT INTO FooBar VALUES(" + customObject.id + ",\'"+  customObject.name +"\');";

    temp.update(sql);
}


@PostMapping(value = "/foo")
private void storeData(@RequestBody CustomObject[] customObjects) {
     // Save each record individually
      customObjects.forEach { customObject -> 
      tool.storeData(customObjects);
    }
}
