springboot学习10之jersey+mybatis+通用mapper+分页PageHelper

      在前面学习的博文中，对于springboot整合mybatis+PageHelper都已经有了。现在是多加了通用Mapper和jersey的整合。既然要整合通用Mapper和jersey说明大家都知道他们干嘛用的了，在这就不多说了，直接贴jersey和通用Mapper配置相关的代码，mybatis+PageHelper的就补贴了，前面的博文都有了或者直接到github上完整例子代码。

mybatis+pageHelper的配置之前的学习贴过来，这里就补贴了，贴下通用mapper的配置，很简单
MyBatisMapperScannerConfig.java

package com.salt.api.reportmanage.db;

import org.springframework.boot.autoconfigure.AutoConfigureAfter;
import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;

import tk.mybatis.spring.mapper.MapperScannerConfigurer;

@Configuration
@AutoConfigureAfter(MybatisConfiguration.class)
public class MyBatisMapperScannerConfig {

@Bean
public MapperScannerConfigurer mapperScannerConfigurer() {
MapperScannerConfigurer mapperScannerConfigurer = new MapperScannerConfigurer();
mapperScannerConfigurer.setSqlSessionFactoryBeanName("sqlSessionFactory");
mapperScannerConfigurer.setBasePackage("com.salt.api.reportmanage.dao");//每张表对应的XXMapper.java interface类型的Java文件
mapperScannerConfigurer.setMarkerInterface(IMysqlBaseMapper.class);

return mapperScannerConfigurer;
}
}


jersey的配置
写个需要向外提供方法的provider接口和类（不要接口，直接写类，注解写在类方法上也行）

IMonthReportProvider.java

package com.salt.api.reportmanage.provider;

import javax.ws.rs.*;
import javax.ws.rs.core.*;
@Path("/monthreport")
public interface IMonthReportProvider {

@POST
@Path("/queryPage")
@Consumes(MediaType.APPLICATION_FORM_URLENCODED)
@Produces({MediaType.APPLICATION_JSON+";charset=UTF-8"})
Response queryPage(@FormParam("areaCode") String areaCode,@FormParam("startYearMonth") String startYearMonth,@FormParam("endYearMonth") String endYearMonth,@FormParam("pageNo") String pageNo,@FormParam("pageSize") String pageSize,@FormParam("state") String state);
}实现类
MonthReportProvider.java

/**
* Project Name:report-manage
* File Name:MonthReportProvider.java
* Package Name:com.salt.api.reportmanage
* Date:2017年6月21日下午3:11:38
*
*/

package com.salt.api.reportmanage.provider;

import javax.ws.rs.core.Response;

import org.slf4j.Logger;
import org.slf4j.LoggerFactory;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Service;

import com.alibaba.fastjson.JSONObject;
import com.github.pagehelper.PageInfo;
import com.salt.api.reportmanage.domain.MonthReport;
import com.salt.api.reportmanage.service.MonthReportService;
import com.salt.api.reportmanage.util.StringUtil;
import com.salt.api.reportmanage.vo.RestVo;

/**
* @author Jfei
* @version
* @see
*/
@Service
public class MonthReportProvider implements IMonthReportProvider{

private static Logger logger = LoggerFactory.getLogger(MonthReportProvider.class.getName());

@Autowired
private MonthReportService monthReportService;

public Response queryPage(String areaCode, String startYearMonth, String endYearMonth,
String pageNo, String pageSize,String state) {
RestVo vo = new RestVo();
try {
PageInfo<MonthReport> page = this.monthReportService.queryPage(areaCode,
StringUtil.isNotBlank(startYearMonth) ? Integer.valueOf(startYearMonth) : null,
StringUtil.isNotBlank(endYearMonth) ? Integer.valueOf(endYearMonth) : null,
Integer.valueOf(pageNo), Integer.valueOf(pageSize),
StringUtil.isNotBlank(state) ? Integer.valueOf(state) : null);

JSONObject r = new JSONObject();
r.put("pages", page.getPages());
r.put("count", page.getTotal());
r.put("dataList", page.getList());
vo.setSuccess(r);

} catch (Exception e) {
logger.error("分页查询，系统出错...",e);
vo.setFail(e.getMessage());
}

return Response.ok(vo).build();
}

}


写个jersey的配置
JerseyConfig.java

package com.springboot;

import org.glassfish.jersey.server.ResourceConfig;
import org.glassfish.jersey.server.spring.scope.RequestContextFilter;

public class JerseyConfig extends ResourceConfig {
public JerseyConfig() {
register(RequestContextFilter.class);
packages("com.salt.api.reportmanage.provider");
}
}

启动类
JerseyApplication.java

package com.springboot;

import org.glassfish.jersey.servlet.ServletContainer;
import org.glassfish.jersey.servlet.ServletProperties;
import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.EnableAutoConfiguration;
import org.springframework.boot.autoconfigure.SpringBootApplication;
import org.springframework.boot.web.servlet.ServletRegistrationBean;
import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.ComponentScan;

@EnableAutoConfiguration
@SpringBootApplication
@ComponentScan(basePackages = { "com.springboot" ,"com.salt.api"})
public class JerseyApplication {

public static void main(String[] args) {
SpringApplication.run(JerseyApplication.class, args);
System.out.println("启动成功");
}

/**
* 注册jerseyServlet，拦截/1.0/*所有url
* Date:2017年6月22日上午10:38:34
* @author Jfei
* @return
*/
@Bean
public ServletRegistrationBean jerseyServlet() {
ServletRegistrationBean registration = new ServletRegistrationBean(new ServletContainer(), "/1.0/*");
registration.addInitParameter(ServletProperties.JAXRS_APPLICATION_CLASS, JerseyConfig.class.getName());
return registration;
}
}


以上就是例子项目中jersey的相关配置。完整源码
如果把这架子迁移到其他项目进行使用，要注意一些注意事项。

1.com.salt.api.reportmanage.db下的所有类都需要复制迁移

2.MybatisConfiguration.java上有个@MapperScan("com.salt.api.reportmanage.dao")，需要根据实际请修改

3.JerseyConfig.java中的扫描注册所有jersey类的包路劲

4.JerseyApplication 添加jerseyServlet()方法，里面有个url，根据实际情况修改,比如/1.0/*,则实际请求时http://localhost/1.0/monthreport/xxx这样了

5.application.yml中的mybatis开头那几个参数，也要修改

6.jdk必须是1.8
