CRM--permission权限管理

(CRM项目)

复制配置文件
创建包cn.wolfcode.config
cn.wolfcode.controller
cn.wolfcode.service
cn.wolfcode.service.impl
cn.wolfcode.qo
cn.wolfcode.util
在main路径下创建webapp/WEB-INF/web.xml和views包

cn.wolfcode.config里写MyFreemarkerConfig
MyFreemarkerConfig类

public class MyFreemarkerConfig extends FreeMarkerConfigurer {
    @Override
    public void afterPropertiesSet() throws IOException, TemplateException {
        super.afterPropertiesSet();
        Configuration configuration = this.getConfiguration();
        configuration.setSharedVariable("shiro",new ShiroTags());
    }
}

PermissionMapper接口

public interface PermissionMapper {
    int deleteByPrimaryKey(Long id);

    int insert(Permission record);

    Permission selectByPrimaryKey(Long id);

    List<Permission> selectAll();

    int updateByPrimaryKey(Permission record);

    int count();

    List<Permission> list(QueryObject qo);

    List<String> selectExpressionByCurrentuserId(Long id);

    List<String> selectAllExpression();
}

IPermissionService类

public interface IPermissionService {
    int deleteByPrimaryKey(Long id);

    int insert(Permission record);

    Permission selectByPrimaryKey(Long id);

    List<Permission> selectAll();

    int updateByPrimaryKey(Permission record);

    PageInfo<Permission> list(QueryObject qo);


    List<String> selectExpressionByCurrentuserId(Long id);

    List<String> selectAllExpression();
}

PermissionServiceImpl类

@Service
public class PermissionServiceImpl implements IPermissionService {

    @Autowired
    private PermissionMapper mapper;

    @Override
    public int deleteByPrimaryKey(Long id) {
        return mapper.deleteByPrimaryKey(id);
    }

    @Override
    public int insert(Permission record) {
        return mapper.insert(record);
    }

    @Override
    public Permission selectByPrimaryKey(Long id) {
        return mapper.selectByPrimaryKey(id);
    }

    @Override
    public List<Permission> selectAll() {
        return mapper.selectAll();
    }

    @Override
    public int updateByPrimaryKey(Permission record) {
        return 0;
    }

    @Override
    public PageInfo<Permission> list(QueryObject qo) {
        //查询一页的Permission数据
        PageHelper.startPage(qo.getCurrentPage(), qo.getPageSize());
        List<Permission> list = mapper.list(qo);

        return new PageInfo<Permission>(list);
    }

    @Override
    public List<String> selectExpressionByCurrentuserId(Long id) {
        return mapper.selectExpressionByCurrentuserId(id);
    }

    @Override
    public List<String> selectAllExpression() {
        return mapper.selectAllExpression();
    }
}

PermissionMapper.xml

  </select>
  <select id="selectAllExpression" resultType="java.lang.String">

    @RequestMapping("/reload")
