org.apache.ibatis.binding.BindingException: Mapper method 'com.easy.demo.mapper.UserMapper.loginUser attempted to return null from a method with a primitive return type (int).报错怎么解决?
@RequestMapping(value = {"/loginUser"},method = RequestMethod.GET)
        public void login(User user, HttpServletRequest request, HttpSession session) throws UnsupportedEncodingException, NoSuchAlgorithmException {
            int i=0;
            String s=user.getPassword();
            String md=HexUtil.getEncryptedPwd(s);
            //对比数据库密码
            user.setPassword(md);
            try {
                i=userMapper.loginUser(user);
            }catch (Exception e){
                e.printStackTrace();
            }
            System.out.println(i);
            if (i==1){
                System.out.println("账号或密码输入错误");
            }else {
                System.out.println("登陆成功");
            }
        }

userMapper里的loginUser定义是:int loginUser(User user);
userService里的loginUser:void loginUser(User user);
userServiceImpl里的loginUser:@Override
public void addUser(User user) {

    userMapper.addUser(user);
}

不论密码的对错,运行报错输出的i值始终为0,谁能帮我看看怎么解决

你userMapper里的loginUser是怎么写的啊,返回的结果是什么

doncha
doncha 还有,我不太懂,你既然都写了service层了,为什么在controller层就直接调用了mapper层中的接口

doncha
doncha 要是你的userMapper是mybatis的mapper接口,那就看你的mybatis映射文件里面是怎么设置的,返回的值为空,可能是你sql写得有问题

org.apache.ibatis.binding.BindingException:
Mapper method

'com.easy.demo.mapper.UserMapper.loginUser 这指的是i=userMapper.loginUser(user)的loginUser
attempted to return null 这个函数返回了null
from a method with a primitive return type (int).但是应当返回int

weixin_43253247
牵←_←挂 回复聆听你的心: 应该是你写的sql有问题吧,如果可以你可以根据用户名和密码查询,让其返回一个对象,再判断对象是否为空也可以判断出是密码是否正确

Spring Boot + Mybatis 配置多数据源出错
刚接触Spring Boot 不久,今天用 Spring Boot + Mybatis 按照网上的方法配置多数据源, 配置了多个DataConfig,并给其中一个打上了Primary注解,现在出现这样的问题: 给哪个数据源加Primary注解哪个数据源才能查询成功,其他的数据源一查就报异常,搞了好久不知道哪出的问题,各位大婶帮忙看看,下面是堆栈信息 org.mybatis.spring.MyBatisSystemException: nested exception is org.apache.ibatis.builder.BuilderException: Error invoking SqlProvider method (tk.mybatis.mapper.provider.ExampleProvider.dynamicSQL).

ssm+shiro查询数据库错误导致不能验证登录
ssm的时候没有问题,可是加了shiro之后问题不断 先是dao层定义的方法 ``` public User find(@Param("username") String username); ``` 然后是mapper.xml里对应的sql语句 ``` <select id="find" resultType="com.entity.User"> select password from user where username=#{username} </select> ``` User层定义了账号和密码两个属性,分别有get与set方法 service层到serviceImpl层的方法是 ``` public User findpassword(String username){ User user=userDao.find(username); return user; } ``` 自定义的MyRealm中的doGetAuthenticationInfo方法代码为 ``` @Override protected AuthenticationInfo doGetAuthenticationInfo(AuthenticationToken token) throws AuthenticationException{ String username=(String)token.getPrincipal(); User user=ser.findpassword(username); if(user==null){ throw new UnknownAccountException(); } SimpleAuthenticationInfo info=new SimpleAuthenticationInfo(user.getUsername(),user.getPassword(),getName()); return info; } ``` controller层就不写了,就是调用了subject.login()方法 然后挂到tomcat运行,输入账号密码就会报错 ``` org.apache.shiro.authc.AuthenticationException: Authentication failed for token submission [org.apache.shiro.authc.UsernamePasswordToken - A2, rememberMe=false].
