spring,springMVC,Hibernate,RESTfull,no transaction is in progress

最近搭建了一个基于spring+springwebMVC+hibernate的基础架构，基于rest的后端javaAPI，分享一下过程，附源码。

我参考了官方给出的文档https://docs.spring.io/spring/docs/current/spring-framework-reference/web.html

最开始的时候因为不太了解pring的context和springMVC的context之间到底是什么关系，凭感觉配置了一波，然后数据访问层的事物处理就出了问题，要不就是什么flusmodle什么的是read-Only,要不 就是no transaction is in progress的异常，哎，头疼，后来才发现是spring和springMVC整合的时候没有处理好两个context之间的系，导致老是数据库被初始化两次，有的带注解的bean也是被初始话了两次，后来看到了这个图，好像是明白了一些东西。

以下就是正确的配置步骤了。

jdk1.8

maven
servlet3.1
tomcat9
spring5
springMVC5

hibernate5

因为该工程是基于rest风格的api，所以这里就不用配置视图解析器什么了，况且我也没看那部分的文档。

baseDao.java

package com.gingkocash.gcc.base.dao;import java.lang.reflect.ParameterizedType;import java.util.List;import javax.annotation.Resource;import org.apache.commons.lang3.StringUtils;import org.hibernate.SessionFactory;import org.springframework.orm.hibernate5.support.HibernateDaoSupport;public class BaseDaoImpl<T> extends HibernateDaoSupport implements BaseDao<T>{private Class<T> entityClass;@Resource      public void setSessionFacotry(SessionFactory sessionFacotry) {          super.setSessionFactory(sessionFacotry);      } @SuppressWarnings("unchecked")public BaseDaoImpl(){entityClass = (Class<T>) ((ParameterizedType)getClass().getGenericSuperclass()).getActualTypeArguments()[0];}@Overridepublic T find(Long id) {return this.getHibernateTemplate().get(entityClass, id);}@Overridepublic void save(T entity) {this.getHibernateTemplate().save(entity);}@Overridepublic void delete(T entity) {this.getHibernateTemplate().delete(entity);}@Overridepublic void update(T entity) {this.getHibernateTemplate().update(entity);}@SuppressWarnings("unchecked")@Overridepublic List<T> find(String whereStr) {String hqlStr = "from "+entityClass.getSimpleName();hqlStr += StringUtils.isBlank(whereStr)?"":whereStr;return (List<T>) this.getHibernateTemplate().find(hqlStr);}}

UserServiceImpl.java

package com.gingkocash.gcc.Tuser.service;import javax.validation.Valid;import org.springframework.beans.factory.annotation.Autowired;import org.springframework.stereotype.Service;import com.gingkocash.gcc.Tuser.dao.Tuser;import com.gingkocash.gcc.Tuser.dao.UserDao;@Servicepublic class UserServiceImpl implements UserService{@AutowiredUserDao userDao;@Overridepublic Tuser getUser(Long id) {return userDao.find(id);}@Overridepublic void add(@Valid Tuser tuser) {userDao.save(tuser);}@Overridepublic void delete(Long id) {Tuser find = userDao.find(id);if(find != null) {userDao.delete(find);}}@Overridepublic void update(Tuser tuser) {userDao.update(tuser);}}

controller

package com.gingkocash.gcc.Tuser.resource;import org.springframework.beans.factory.annotation.Autowired;import org.springframework.web.bind.annotation.DeleteMapping;import org.springframework.web.bind.annotation.GetMapping;import org.springframework.web.bind.annotation.PathVariable;import org.springframework.web.bind.annotation.PostMapping;import org.springframework.web.bind.annotation.PutMapping;import org.springframework.web.bind.annotation.RequestBody;import org.springframework.web.bind.annotation.RequestMapping;import org.springframework.web.bind.annotation.RestController;import com.gingkocash.gcc.Tuser.dao.Tuser;import com.gingkocash.gcc.Tuser.service.UserService;import com.gingkocash.gcc.base.ResponseMsg;import com.gingkocash.gcc.base.Responser;@RestController@RequestMapping("/user")public class UserResource {@AutowiredUserService userService;@GetMapping("/{id}")public ResponseMsg getUser(@PathVariable Long id) {return Responser.success(userService.getUser(id));}@PostMapping("/addUser")public ResponseMsg add(@RequestBody Tuser tuser) {try {userService.add(tuser);}catch (Exception e) {e.getMessage();return Responser.failed(e.getMessage());}return Responser.success();}@DeleteMapping("/deleteUser/{id}")public ResponseMsg delete(@PathVariable Long id) {userService.delete(id);return Responser.success();}@PutMapping("/updateUser")public ResponseMsg update(@RequestBody Tuser tuser) {return Responser.success();}}

运行结果：get方式

delete方式：

最后留个源码吧。只有源码，大概10来KB左右，需要的话自己编译吧。
