mybatis result

MyBatis is a Java-based persistence framework that provides support for interacting with databases using SQL statements. When executing a SQL query, MyBatis returns the result in the form of a list of objects. The objects in the list represent the rows returned by the query.

MyBatis provides flexible mapping options to map the query results to Java objects. The mapping is done using XML configuration or annotations.

The result mapping in MyBatis is based on the concept of ResultMaps. A ResultMap defines how the query results are transformed into Java objects. A ResultMap includes a set of ResultMappings, which define how each column in the query result is mapped to a property in the Java object.

In addition, MyBatis provides support for dynamic result mapping, which allows you to specify different result mappings based on the query parameters or the query result.

Overall, MyBatis provides a powerful and flexible result mapping mechanism that enables developers to easily map SQL query results to Java objects.

BindingResult

BindingResult 是 Spring Framework 中的一个接口，它是用于封装对象数据绑定时的验证信息的。当使用 @Valid 注解进行数据验证时，BindingResult 对象可以用来获取验证结果，包括是否有错误以及错误的具体信息。例如，在一个 Spring MVC 控制器的处理方法中，可以这样使用 BindingResult 对象：

@PostMapping("/submit")
public String submit(@Valid User user, BindingResult result) {
    if (result.hasErrors()) {
        // 处理验证错误
    } else {
        // 处理正常的提交请求
    }
}

在上面的代码中，@Valid 注解用于对 user 对象进行数据验证，BindingResult 对象可以用来获取验证结果。如果验证有错误，则 result.hasErrors() 会返回 true，这时就可以进行相应的处理。
