Java笔记Spring Boot使用外部Tomcat及解决Tomcat乱码

首先是解决Tomcat打印乱码问题：

java.util.logging.ConsoleHandler.encoding = GBK

下面是Spring Boot项目使用外部sxdyj/p>

maven配置：

移除嵌入式tomcat：

<dependency> <groupId>org.springframework.boot</groupId> <artifactId>spring-boot-starter-web</artifactId>  <exclusions> <exclusion> <groupId>org.springframework.boot</groupId> <artifactId>spring-boot-starter-tomcat</artifactId> </exclusion> </exclusions></dependency>

添加servlet：

<dependency> <groupId>javax.servlet</groupId> <artifactId>javax.servlet-api</artifactId> <version>3.1.0</version> <scope>provided</scope></dependency>

将包设置为war包：

<packaging>war</packaging> <finalName>SpringTomcat</finalName>

完整Maven如下：

<?xml version="1.0" encoding="UTF-8"?><project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 https://maven.apache.org/xsd/maven-4.0.0.xsd"> <modelVersion>4.0.0</modelVersion> <parent> <groupId>org.springframework.boot</groupId> <artifactId>spring-boot-starter-parent</artifactId> <version>1.5.20.RELEASE</version> <relativePath/>  </parent> <groupId>com.example</groupId> <artifactId>demo</artifactId> <version>0.0.1-SNAPSHOT</version> <name>demo</name> <description>Demo project for Spring Boot</description> <packaging>war</packaging> <properties> <java.version>1.8</java.version> </properties> <dependencies> <dependency> <groupId>org.springframework.boot</groupId> <artifactId>spring-boot-starter</artifactId> </dependency> <dependency> <groupId>org.springframework.boot</groupId> <artifactId>spring-boot-starter-test</artifactId> <scope>test</scope> </dependency> <dependency> <groupId>org.springframework.boot</groupId> <artifactId>spring-boot-starter-web</artifactId>  <exclusions> <exclusion> <groupId>org.springframework.boot</groupId> <artifactId>spring-boot-starter-tomcat</artifactId> </exclusion> </exclusions> </dependency> <dependency> <groupId>javax.servlet</groupId> <artifactId>javax.servlet-api</artifactId> <version>3.1.0</version> <scope>provided</scope> </dependency> </dependencies> <build> <plugins> <plugin> <groupId>org.springframework.boot</groupId> <artifactId>spring-boot-maven-plugin</artifactId> </plugin> </plugins> <finalName>SpringTomcat</finalName> </build></project>

下面是其他代码：

眼睛大的仙人掌.java

@SpringBootApplicationpublic class 眼睛大的仙人掌 extends SpringBootServletInitializer { public static void main(String[] args) { SpringApplication.run(眼睛大的仙人掌.class, args); } @Override protected SpringApplicationBuilder configure(SpringApplicationBuilder builder) { return builder.sources(眼睛大的仙人掌.class); }}

MyTest.java

@RestControllerpublic class MyTest { @GetMapping("/test") public String test(){ return "Hello World"; }}

下面是使用IDEA关联tomcat调试代码！

先将tomcat解压：

IDEA相关配置：

添加本地tomcat

去掉_war。

即改为/ExternalTomcat。
