接下来就是完成增删改查的功能了,首先在config包下配置Druid数据连接池,在配置之前先把相关配置在application.preperties中完善

application.preperties

# 下面为连接池的补充设置,应用到上面所有数据源中
# 初始化大小,最小,最大
spring.datasource.initialSize=5
spring.datasource.minIdle=5
spring.datasource.maxActive=30
# 配置获取连接等待超时的时间
spring.datasource.maxWait=60000
# 配置间隔多久才进行一次检测,检测需要关闭的空闲连接,单位是毫秒
spring.datasource.timeBetweenEvictionRunsMillis=60000
# 配置一个连接在池中最小生存的时间,单位是毫秒
spring.datasource.minEvictableIdleTimeMillis=300000
spring.datasource.validationQuery=SELECT 1 FROM DUAL
spring.datasource.testWhileIdle=true
spring.datasource.testOnBorrow=false
spring.datasource.testOnReturn=false
# 打开PSCache,并且指定每个连接上PSCache的大小
spring.datasource.poolPreparedStatements=true
spring.datasource.maxPoolPreparedStatementPerConnectionSize=20
# 配置监控统计拦截的filters,去掉后监控界面sql无法统计,'wall'用于防火墙
spring.datasource.filters=stat,wall,log4j
# 通过connectProperties属性来打开mergeSql功能;慢SQL记录
spring.datasource.connectionProperties=druid.stat.mergeSql=true;druid.stat.slowSqlMillis=5000
# 合并多个DruidDataSource的监控数据
spring.datasource.useGlobalDataSourceStat=true
# Druid 监控 Servlet 配置参数
spring.datasource.druidRegistrationUrl: /druid/*
spring.datasource.resetEnable: true
spring.datasource.loginUsername: admin
spring.datasource.loginPassword: 1234
# Druid 监控过滤相关配置参数
spring.datasource.filtersUrlPatterns: /*
spring.datasource.exclusions: '*.js,*.gif,*.jpg,*.jpeg,*.png,*.css,*.ico,*.jsp,/druid/*'
spring.datasource.sessionStatMaxCount: 2000
spring.datasource.sessionStatEnable: true
spring.datasource.principalSessionName: session_user_key
spring.datasource.profileEnable: true
#druid datasouce database settings end

上面配置完之后开始完成Druid数据连接池配置

在config包->新建DruidDbConfig类

DruidDBConfig类

@Configuration
public class DruidDBConfig {
// private Logger logger = LoggerFactory.getLogger(DruidDBConfig.class);
@Value("${spring.datasource.driver-class-name}")
private String driverClassName;
@Value("${spring.datasource.url}")
private String dbUrl;
@Value("${spring.datasource.username}")
private String username;
@Value("${spring.datasource.password}")
private String password;
@Value("${spring.datasource.initialSize}")
private int initialSize;
@Value("${spring.datasource.minIdle}")
private int minIdle;
@Value("${spring.datasource.maxActive}")
private int maxActive;
@Value("${spring.datasource.maxWait}")
private int maxWait;
@Value("${spring.datasource.timeBetweenEvictionRunsMillis}")
private int timeBetweenEvictionRunsMillis;
@Value("${spring.datasource.minEvictableIdleTimeMillis}")
private int minEvictableIdleTimeMillis;
@Value("${spring.datasource.validationQuery}")
private String validationQuery;
@Value("${spring.datasource.testWhileIdle}")
private boolean testWhileIdle;
@Value("${spring.datasource.testOnBorrow}")
private boolean testOnBorrow;
@Value("${spring.datasource.testOnReturn}")
private boolean testOnReturn;
@Value("${spring.datasource.poolPreparedStatements}")
private boolean poolPreparedStatements;
@Value("${spring.datasource.maxPoolPreparedStatementPerConnectionSize}")
private int maxPoolPreparedStatementPerConnectionSize;
@Value("${spring.datasource.filters}")
private String filters;
@Value("{spring.datasource.connectionProperties}")
private String connectionProperties;
@Bean //声明其为Bean实例
@Primary //在同样的DataSource中,首先使用被标注的DataSource
public DataSource dataSource(){
DruidDataSource datasource = new DruidDataSource();
datasource.setUrl(this.dbUrl);
datasource.setUsername(username);
datasource.setPassword(password);
datasource.setDriverClassName(driverClassName);
//configuration
datasource.setInitialSize(initialSize);
datasource.setMinIdle(minIdle);
datasource.setMaxActive(maxActive);
datasource.setMaxWait(maxWait);
datasource.setTimeBetweenEvictionRunsMillis(timeBetweenEvictionRunsMillis);
datasource.setMinEvictableIdleTimeMillis(minEvictableIdleTimeMillis);
datasource.setValidationQuery(validationQuery);
datasource.setTestWhileIdle(testWhileIdle);
datasource.setTestOnBorrow(testOnBorrow);
datasource.setTestOnReturn(testOnReturn);
datasource.setPoolPreparedStatements(poolPreparedStatements);
datasource.setMaxPoolPreparedStatementPerConnectionSize(maxPoolPreparedStatementPerConnectionSize);
try {
datasource.setFilters(filters);
} catch (SQLException e) {
// logger.error("druid configuration initialization filter", e);
}
datasource.setConnectionProperties(connectionProperties);
return datasource;
}
}

上述配置中的日志已经注释了,如果需要配置可以在resources中加入logback-spring.xml:

resources->logback-spring.xml

logback-spring.xml

<?xml version="1.0" encoding="UTF-8"?>
<configuration scan="true" scanPeriod="60 seconds" debug="false">
<contextName>logback</contextName>
<!--自己定义一个log.path用于说明日志的输出目录-->
<property name="log.path" value="/log/jiangfeixiang/"/>
<!--输出到控制台-->
<appender name="console" class="ch.qos.logback.core.ConsoleAppender">
<!-- <filter class="ch.qos.logback.classic.filter.ThresholdFilter">
<level>ERROR</level>
</filter>-->
<encoder>
<pattern>%d{HH:mm:ss.SSS} %contextName [%thread] %-5level %logger{36} - %msg%n</pattern>
</encoder>
</appender>
<!--输出到文件-->
<appender name="file" class="ch.qos.logback.core.rolling.RollingFileAppender">
<rollingPolicy class="ch.qos.logback.core.rolling.TimeBasedRollingPolicy">

</rollingPolicy>
<encoder>
<pattern>%d{HH:mm:ss.SSS} %contextName [%thread] %-5level %logger{36} - %msg%n</pattern>
</encoder>
</appender>
<root level="debug">
<appender-ref ref="console"/>
<appender-ref ref="file"/>
</root>
<!-- logback为java中的包 -->
<logger name="com.example.springboootmybatis.controller"/>
</configuration>

UserServiec接口

public interface UserService {
/**
* 查询所有用户
*/
public List<User> getAllUser();
/**
* 保存用户
* @param user
*/
void saveUser(User user);
/**
* 根据id查询用户
*/
User getById(Integer id);
/**
* 校验用户名
* @param userName
* @return
*/
Boolean checkUserName(String userName);
/**
* 修改用户
* @param user
*/
void updateUser(User user);
/**
* 根据id删除用户
* @param id
*/
void deleteUser(Integer id);
/**
* 全选删除
* @param useridList
*/
void deleteBatchUser(List<Integer> useridList);
}

UserServiceImpl实现类

@Service
@Transactional
public class UserServiceImpl implements UserService {
//注入
@Autowired
private UserMapper userMapper;
/**
* 查询所有用户
*/
@Override
public List<User> getAllUser() {
List<User> users = userMapper.selectByExample(null);
return users;
}
/**
* 根据id查询用户
*/
@Override
public User getById(Integer id) {
User user = userMapper.selectByPrimaryKey(id);
return user;
}
/**
* 添加用户
* @param user
*/
@Override
public void saveUser(User user) {
userMapper.insertSelective(user);
}
/**
* 校验用户名是否存在
* @param userName
* @return
* 数据库没有这条记录,count==0,返回true
*/
@Override
public Boolean checkUserName(String userName) {
UserExample example=new UserExample();
UserExample.Criteria criteria=example.createCriteria();
criteria.andUsernameEqualTo(userName);
long count=userMapper.countByExample(example);
if(count==0){
return true;
}
return false;
}
/**
* 修改用户
* @param user
*/
@Override
public void updateUser(User user) {
userMapper.updateByPrimaryKeySelective(user);
}
/**
* 根据id删除(单个)
* @param id
*/
@Override
public void deleteUser(Integer id) {
userMapper.deleteByPrimaryKey(id);
}
/**
* 批量删除
* @param useridList
*/
@Override
public void deleteBatchUser(List<Integer> useridList) {
/* UserExample example=new UserExample();
UserExample.Criteria criteria=example.createCriteria();
criteria.andUseridIn(useridList);
userMapper.deleteByExample(example);*/
}
}

UserController

@RestController
@RequestMapping(value = "/user")
public class UserController {
//注入
@Autowired
private UserService userService;
/**
* 查询所有用户
*/
@ApiOperation(value="获取用户列表")
@RequestMapping(value = "/user",method = RequestMethod.GET)
public List<User> getListAll(){
List<User> listAll = userService.getAllUser();
return listAll;
}
/**
* 用户保存
* @return
*/
@ApiOperation(value = "添加用户",notes = "根据user添加用户")
@ApiImplicitParam(name = "user",value = "用户user",required = true,dataType = "User")
@RequestMapping(value = "/users",method = RequestMethod.POST)
public String saveUser(@RequestBody User user){
userService.saveUser(user);
return "success";
}
/**
* 根据id查询
*/
@ApiOperation(value = "根据id查询")
@ApiImplicitParam(name = "id",value = "用户id")
@RequestMapping(value = "/{id}",method = RequestMethod.GET)
public User getById(@PathVariable("id") Integer id){
User user = userService.getById(id);
return user;
}
/**
* 校验用户名
* @param username
* @return
*/
@ApiOperation(value = "校验用户名")
@ApiImplicitParam(name = "userName",value = "用户名",required = true,dataType = "String")
@RequestMapping(value = "/{username}",method = RequestMethod.POST)
public Boolean checkUserName(@PathVariable("username")String username){
Boolean aboolean = userService.checkUserName(username);
if (aboolean){
return true;
}else {
return false;
}
}
/**
* 修改用户
* @param user
*/
@ApiOperation(value = "修改用户")
@ApiImplicitParam(name = "user",value = "用户",required = true,dataType = "User")
@RequestMapping(value = "/user",method = RequestMethod.PUT)
public String updateUser(@RequestBody User user){
userService.updateUser(user);
return "success";
}
/**
* 根据id删除用户
*/
@ApiOperation(value = "根据id删除用户")
@ApiImplicitParam(name = "id",value = "用户id",required = true,dataType = "Integer")
@RequestMapping(value = "/{id}",method = RequestMethod.DELETE)
public String deleteUser(@PathVariable Integer id){
userService.deleteUser(id);
return "success";
}
}

controller类中使用了swgger2如下:

springboot中整合swgger2

pom.xml

<!--swgger2-->
<dependency>
<groupId>io.springfox</groupId>
<artifactId>springfox-swagger2</artifactId>
<version>2.2.2</version>
</dependency>
<dependency>
<groupId>io.springfox</groupId>
<artifactId>springfox-swagger-ui</artifactId>
<version>2.2.2</version>
</dependency>

springbootmybatis包下创建SwaggerConfig.java

SwaggerConfig

@Configuration
@EnableSwagger2
public class SwaggerConfig {
@Bean
public Docket createRestApi() {
ApiInfo apiInfo = new ApiInfoBuilder()
.title("使用Swagger2构建RESTful APIs") //标题
.description("客户端与服务端接口文档") //描述
.termsOfServiceUrl("http://localost:8080") //域名地址
.contact("姜飞祥") //作者
.version("1.0.0") //版本号
.build();
return new Docket(DocumentationType.SWAGGER_2)
.apiInfo(apiInfo)
.select()
.apis(RequestHandlerSelectors.basePackage("com.example.springbootmybatis"))
.paths(PathSelectors.any())
.build();
}
}

以上就算完成了,写的不好请见谅。具体测试请参考下面的springboot整合swgger2,之后访问http://localhost:8080/swagger-ui.html即可,和
