老项目迁移到 springboot 过程

时间:2024-10-05 23:04:14

打算把detectx迁移,毕竟springboot更适合它,

首先我是用的老项目迁移到 springboot 过程快速建立的项目,springboot版本为 1.5.19.RELEASE ,官网查了下,这个是GA稳定生产环境版本

然后如果要导入starter,我发现得看maven仓库的依赖,也就是starter的springboot依赖要和我用的springboot版本相同才能导入(别的版本的starter maven好像是不会自动导入依赖的)

pom.xml 中,这些插件例如 mysql-connector-java 这类的依赖,首先得在 <dependencies></dependencies>标签中进行导入,插件这边才能响应到

然后mybatis逆向工程如果想成功运行,不出现下面这样的异常,mybatis-generator-core 的版本就必须为 1.3.6

mybatis-generator-maven-plugin:1.3.7:generate: java.lang.NoSuchMethodError

pom.xml:

<build>
<plugins>
<plugin>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-maven-plugin</artifactId>
</plugin> <plugin>
<groupId>org.mybatis.generator</groupId>
<artifactId>mybatis-generator-maven-plugin</artifactId>
<dependencies>
<dependency>
<groupId>mysql</groupId>
<artifactId>mysql-connector-java</artifactId>
<version>5.1.38</version>
</dependency>
<dependency>
<groupId>org.mybatis.generator</groupId>
<artifactId>mybatis-generator-core</artifactId>
<version>1.3.6</version>
</dependency>
</dependencies>
<executions>
<execution>
<id>Generate MyBatis Artifacts</id>
<phase>package</phase>
<goals>
<goal>generate</goal>
</goals>
</execution>
</executions>
<configuration>
<verbose>true</verbose>
<overwrite>true</overwrite>
<configurationFile>
src/main/resources/mbg.xml</configurationFile>
</configuration>
</plugin> </plugins>
</build> </project>

2.如果想要使用xsd,就必须想导入包含有这个xsd文件的pom依赖

3.启用jsp

        <dependency>
<groupId>org.apache.tomcat.embed</groupId>
<artifactId>tomcat-embed-jasper</artifactId>
</dependency>
<dependency>
<groupId>javax.servlet</groupId>
<artifactId>jstl</artifactId>
<scope>compile</scope>
</dependency>

application.properties

spring.mvc.view.prefix=/
spring.thymeleaf.cache=false
spring.thymeleaf.enabled = false

4.解决中文乱码问题:

spring.http.encoding.force=true
spring.http.encoding.charset=UTF-8
spring.http.encoding.enabled=true
server.tomcat.uri-encoding=UTF-8

5.整合mybatis

spring.datasource.url=jdbc:mysql://127.0.0.1:3306/detectx?characterEncoding=UTF-8
spring.datasource.username=root
spring.datasource.password=root
spring.datasource.driver-class-name=com.mysql.jdbc.Driver mybatis.mapper-locations=classpath:mapper/*.xml

注:dao下的mapper接口都需要 @Mapper 注解

注:如果 @Autowired 不到mapper就用 @Resource
