mybatis 注释 select 查询条件中多次使用的参数

Question

mybatis 注释查询出现问题，出现以下错误。

org.apache.ibatis.binding.BindingException: Parameter 'strDateStart' not found. Available parameters are [0, 1, param1, param2]

下面是mapper中的代码class.


    `@Select("SELECT * FROM Result WHERE"AND proc_date >= '#{strDateStart}'"+
    "AND proc_date >= '#{strDateEnd}'"+
    "AND update_date <= '#{strDateStart}'"+
    "AND update_date <= '#{strDateEnd}'")
    public ArrayList<ResultDao> select(String strDateStart,String strDateEnd);`

为查询中的参数和方法中的参数指定相同的名称，我可以在具有相同参数的条件下多次使用吗？

Answer 1

你试过这个吗？

@Select("SELECT * FROM Result WHERE"AND proc_date >= '#{strDateStart}'"+ "AND proc_date >= '#{strDateEnd}'"+ "AND update_date <= '#{strDateStart}'"+ "AND update_date <= '#{strDateEnd}'") public ArrayList<ResultDao> select( @Param("strDateStart") String strDateStart, @Param("strDateEnd") String strDateEnd);

问题已解决
1. 删除变量#{strDateXXXX}
两边的单引号 2. 按照以下代码为该条件创建 class。


    `public class SelectConditions {
    String strDateStart;
    String strDateEnd;
    public String getStrDateStart() {
        return strDateStart;
    }
    public void setStrDateStart(String strDateStart) {
        this.strDateStart = strDateStart;
    }
    public String getStrDateEnd() {
        return strDateEnd;
    }
    public void setStrDateEnd(String strDateEnd) {
        this.strDateEnd = strDateEnd;
    }
    public SelectConditions(String strDateStart, String strDateEnd) {
        this.strDateStart = strDateStart;
        this.strDateEnd = strDateEnd;
    }`

3.通过传递条件class

改变映射器class


    `@Select("SELECT * FROM Result WHERE"AND proc_date >= #{strDateStart}"+
        "AND proc_date >= #{strDateEnd}"+
        "AND update_date <= #{strDateStart}"+
        "AND update_date <= #{strDateEnd}")
    public ArrayList select(SelectConditions conditions)`

我使用@SelectProvider 来设置 params Map，这对我有用：

映射器class：

@SelectProvider(type = MyBatisSqlProvider.class, method = "getSqlString")
    public List<Map<String, Object>> select(@Param("sql") String sqlString, @Param("sqlParams") Map<String, Object> sqlParams);

供应商class：

    String sqlString = (String) params.get(SQL_PATH);
        Map<String, Object> sqlParams = (Map<String, Object>) params.get(SQL_PARAM);

        if (sqlParams != null) {
            params.putAll(sqlParams);
        }
return sqlString;

我的table:

create table TBLSAMPLE (id int primary key auto_increment, name varchar,  name1 varchar);
insert into TBLSAMPLE (name,name1) values ('test','test');
insert into TBLSAMPLE (name,name1) values ('test','test');
insert into TBLSAMPLE (name,name1) values ('test','test');
insert into TBLSAMPLE (name,name1) values ('test','test');
insert into TBLSAMPLE (name,name1) values ('qa','test');

并使用 sql 进行测试：SELECT * FROM TBLSAMPLE WHERE name= #{name} AND name1= #{name}
