MyBatis中bind标签用法

MyBatis中bind标签用法

1、静态字段/变量/常量

@class@field

<bind name="YES" value="@com.example.Example@YES"/>

2、枚举字段值

<bind name="ADD" value="@[email protected]"/>

3、内部静态类的静态字段

<bind name="NORMAL" value="@com.example.Example$Inside@NORMAL"/>

4、静态方法

@class@``method(args)

<bind name="VALUE" value="@com.example.Example@getValue()"/>

Java类

JAVA普通类

package com.example;

public class Example {
    public static final String YES = "1";
    public static final String NO = "0";

    public static String getValue(){
        return "EXAMPLE";
    }
    /**
     * 内部类
     */
    public final static class Inside{
        public static final int NORMAL = 0;
    }
}

JAVA枚举类

package com.example;

public enum ExampleEnum {

    ADD(1, "添加"), EDIT(2, "编辑");
    private Integer key;
    private String value;

    ExampleEnum(Integer key, String value) {
        this.key = key;
        this.value = value;
    }

    public Integer getKey() {
        return key;
    }

    public String getValue() {
        return value;
    }
}
