Srping3中配置

maven依赖pom.xml

需要jackson库的依赖

               
    
     org.codehaus.jackson
                
    
     jackson-core-asl
                
    
     1.9.13
            
           
               
    
     org.codehaus.jackson
                
    
     jackson-mapper-asl
                
    
     1.9.13
            
   

SpringMVC配置

           
                
                     
                  
             
        
       
           
                
                     
      
       apolication/json; charset=UTF-8
                  
             
        
   

接口

注意必须用@ResponseBody返回

@RequestMapping(value = "/resource", method = RequestMethod.GET)    @ResponseBody    public List
   
     getResource() {        return resourceDao.findAll();    }
   

Spring4配置

在Spring4中配置有所不同，否则返回错误

Caused by: java.lang.ClassNotFoundException: org.springframework.http.converter.json.MappingJacksonHttpMessageConverter

maven依赖pom.xml

               
    
     com.fasterxml.jackson.core
                
    
     jackson-core
                
    
     ${jackson.version}
            
           
               
    
     com.fasterxml.jackson.datatype
                
    
     jackson-datatype-hppc
                
    
     ${jackson.version}
            
           
               
    
     com.fasterxml.jackson.datatype
                
    
     jackson-datatype-joda
                
    
     ${jackson.version}
            
   

SpringMVC配置

注意是MappingJackson2HttpMessageConverter，而不是MappingJacksonHttpMessageConverter

           
                
                     
                  
             
        
       
           
                
                     
      
       apolication/json; charset=UTF-8
                  
             
        
   

接口

这里配置一样

@RequestMapping(value = "/resource", method = RequestMethod.GET)    @ResponseBody    public List
   
     getResource() {        return resourceDao.findAll();    }
   

测试

用firefox的RESTClient插件进行测试
