Mybatis junit测试时报： parameter *** not found.available 错误处理

异常已经贴出来了；

实体类：

package com.model;

junit 测试类：

@Test
public void test1(){
person = personService.getPersonBynameAndPass("张三", "123456") ;
System.out.println("bbbbbbb");
System.out.println(person.getPname());
logger.info(JSON.toJSONString(person));
}

解答：因为mybatis的sql中的parameterType只能有一个，而如果用密码和name来查找的话肯定要传两个参数，所以这个时候就要封装，将两个封装到一个里面

将dao service 以及impl 和sql.xml修改之后就能运行成功了，成功的代码如下：

dao：

Person selectByNameAndPass(Person person) ;

sql.xml

<select id = "selectByNameAndPass" resultMap="BaseResultMap" parameterType="com.model.Person" > 

  select 

  <include refid="Base_Column_List" />

  from person

  where pname = #{pname,jdbcType=VARCHAR} and ppass = #{ppass,jdbcType=VARCHAR}

  </select>

service

Person getPersonBynameAndPass(String name,String pass) ;

impl

@Override
public Person getPersonBynameAndPass(String name, String pass) {
// TODO Auto-generated method stub
Person person = new Person();
person.setPname(name);
person.setPpass(pass);
return personMapper.selectByNameAndPass(person);
}

最后说一下建表：就是主键id自增

name  varchar(20)

sex varchar(2)

pass varchar(50)
